CFD Analysis to Analyze Thermal Characteristics of a Heat Exchanger Handling Combination of Dimple Ribs

It takes a lot of energy to have a good life. For living and working, humans nowadays rely on an abundant and constant source of power. Because energy is depleting at such a rapid rate, it has become important to use heat more efficiently, which necessitates that we preserve. As a result of the global energy crisis, many researchers have worked to improve the efficiency of thermal systems and reduce the size and thus energy consumption rates, which is one of the most critical problems due to the large and continuing increase in consumption, the increasing scarcity of energy resources, and the high cost. A 3 dimensional numerical 3 D simulation was used to evaluate the thermal properties of a heat exchanger managing a combination of dimple ribs. Handling air flow velocity through the channel was varied from 3.97 to 5.80 m s. is the subject of this study. The heat transfer physiognomies of a heat exchanger managing a combination of dimple ribs were studied using the simulation tool ANSYS 19.2. The numerical results showed that the combination of dimple ribs enhanced heat transfer significantly more than the dimple. In comparison, the average Nusselt number of a combination of dimple ribs is 4.28 percent higher than that of a channel with dimpled Plate.

Analysis of High Rise Building Connection for Square Hollow Beam and Column Using Fem Software Abaqus

Most of the steel structures in India are made of conventional steel sections such as angle, channel and beam sections . However, new hollow steel sections such as square and rectangular hollow sections are gaining popularity in recent steel constructions due to a number of advantages such as its higher strength to weight ratio, better fire resistance properties, higher radius of gyration, lesser surface area, etc. This type of hollow sections can save cost up to 30 to 50 over the conventional steel sections Tata Steel brochure, 2012 17 . But unlike the conventional steel sections these hollow sections do not have standard connection details available in design code or in published literature. To overcome this problem the objective of the present study was identified to develop a suitable and economic connection detail between two square hollow sections which should be capable of transmitting forces smoothly and easy to be fabricated. To achieve the above objective, a square hollow beam to square hollow column connection was selected and modeled in commercial finite element software ABAQUS. This model was analyzed for nonlinear static pushover analysis considering a number of connection details. Following four alternative scheme of connection details were selected for this study i using end plate, ii using angle section, iii using channel sections, and iv using collar plates. The base model rectangular hollow beam welded to one face of the rectangular hollow column is also studied for reference. The performance of the selected connection details are compared and the best performing connection details is recommended for rectangular hollow beam to rectangular hollow column joints. The result shows that the load carrying capacity of the joint and the maximum deformation capacity is highly sensitive to the type of connection used. Also, the location of formation of plastic hinges in the structure which can beat joint or at beam depends highly on the type of connection used.

Cost Optimization of Construction Projects by Using Advance Methods and Advanced Materials

Construction industry could be considered as a very important sector for development all over the World and the construction cost is the most important element in it. The construction project can vary from extremely profitable to barely worth it and sometimes end up costing the contractor more than what he or she is getting paid to complete it. In construction industry the aim of project control is to ensure the projects finish on time, within budget and achieving other project activities. Time and cost are two main concerns which increase importance of cost reduction techniques. Reduction of cost of construction is a constant goal for construction industry. One way of reducing construction cost is to develop innovative technologies as well as methodologies to increase productivity. This study was carried out to identify the factors affecting construction cost. The factors were identified based on case studies and market surveys. In this paper, we have studied different techniques for optimization. To minimize the construction cost and duration at each phase is important. It is a need to meet the present day requirements and to complete the project within the estimated time, cost, and available resources. Mainly affecting the factor on cost of project is delay in project and material. Several methods have been developed and applied to analyze the time cost problems, but they can optimize only one parameter. Various low cost material also suggested for optimizing the cost of project along with maintaining the quality and strength of the project. Also various mathematical method and software based models studied for optimization. This study centers on assessing the cost of construction project and compare the construction cost with the optimized cost of the same building by using advance construction techniques and materials. Outcomes of cost study suggest that the construction cost of residential building project is reduced by 20 30 , 10 20 in infrastructural projects and 25 35 in industrial projects than the construction cost.

An Experimental Study on Soil Stabilization by Using Bio Enzymes

Normal The conventional methods are time consuming and are not efficiently feasible. Hence there is a need to find the other possible ways to assure the performance as well as economical criteria. These enzymes have been confirmed to be very effective and economical. Another benefit of the bioenzyme is that these are environment friendly. The efficiency of bio enzyme depends upon the quantity of dosage, type of soil and curing period. In our country vast areas consist of black soils. As the conservative soil stabilizers like gravel, sand and others are depleting and becoming dear day by day at a very rapid pace, it becomes essential to look towards for alternative eco friendly stabilizers as their alternate. Recently a lot of Bio enzymes have emerged as cost effective stabilizers for soil stabilization. Some such type of bio enzyme, like Terazyme, bagasse ash, lime etc. has been used in the present work. Recently many Bio enzymes have emerged as value powerful stabilizers for soil stabilization. One such bio enzyme, Terrazyme, has been used within side the gift paintings to take a look at its impact at the Unconfined Compressive electricity of the Black Cotton soil. It has been located that Terrazyme dealt with Black Cotton soil suggests vast boom in Unconfined Compressive electricity with longer curing period.

Bee Hive Status Control System

Nomadic beekeeping, one of the branches of honey production, requires the presence of hives in different places at different times of the year. Adapting to the difficult conditions of nomadic beekeeping forces the living conditions and standards. With the help of todays technology, it is necessary to continue this profession more easily and prevent the opposite situations in the nomadic beekeeping sector. This study can be followed up at certain intervals from distant distances. The information that will be received through the sensors in the Hive and from the environment will be sent to the central system through radio frequency waves and the information that will be analyzed will be transmitted to the user via SMS. The bee hive, which is far from the hive farm, will have information about the hive. This will make nomadic beekeeping more efficient.

Comparative Analysis and Design of Voided Slab and RCC I Girder with Solid Slab in Bridge Structure

This thesis is basically based on the comparison of the use of voided slab, RCC Solid slab and RCC Girder. In this study analysis and cost comparison of RCC Solid slab deck, RCC Voided slab deck and RCC Girder is done for superstructure spanning 20 m length. Solid slabs having greater span are uneconomical due to heavy dead load of concrete. To make it economical longitudinal beams are provided for spans greater than 10.0 m. Reinforced Concrete Girder is generally adopted for a fly over or road bridge, but in case of a river bridge with submersible superstructure, the longitudinal beams creates obstruction to the flow of water and results in additional stresses in cross direction on beams. To reduce the self weight of concrete without sacrificing its flexural strength, in solid slab voids are incorporated in concrete section. This technic offers many advantages over a conventional solid concrete slab like reduced material use, lower total cost of construction, and increased structural efficiency. This report also shows that the dead load of bridge superstructure can be reduced by providing voids in concrete where it is unnecessarily provided. Presence of voids within the concrete structure makes analysis of structure very complicated. The analysis of RCC Solid slab, RCC Girder and RCC voided slab deck for various loads as specified in IRC is done using staad pro software for span length of 20 m and width of 15.10 m. The analysis illustrates the behavior of bending moments, Shear Force, displacements, reactions for various load conditions. It is concluded that use of voided slab is more feasible for 20 m length and 15.10 m width. It is also economical as compared to solid slab and Reinforced concrete Girder.
