Relation between Area of Opening and Range of Splash of Testing Fluid during Hydro Testing of Knife Gate Valve

Determination of relations between various variables is necessary while designing any experiment. Various methods may be employed depending on the availability of resources at the experimental setup. However, while the experiment is being designed, it is equally important that the same is backed by

theoretical formulae. If not derived or proved already, new ones can definitely be derived using first principles. In this study, a relation between the area of opening and range of splash shall be derived. The aim of this relation shall be to get a basic comprehension of the variation in parameters in relation to the range of splash of testing fluid. The concepts of range of splash and area of opening shall be reported at the initial stage. The area of opening shall then be determined using the method of integration considering variables involved in the formulation. On obtaining an expression, a relation between the area of opening and the range of splash shall be derived. Towards the end a conclusion shall be drawn reporting the proportional relations between the variables.

Design, Performance Evaluation and Synthesis of Sulfonated Carbon Based Catalyst for Hydrolysis of Microcrystalline Cellulose

Microcrystalline cellulose can be converted into valuable products such as glucose via hydrolysis reaction at mild condition using sulfonated carbon catalyst. A sulfonated carbon material was prepared by carbonization of bamboo sawdust followed by sulfonation. Prepared catalyst was studied for its ability to catalyze microcrystalline cellulose yield via hydrolysis reaction. Three carbon based catalysts at three different temperatures 400, 450 and 500 were prepared. The sulfonated catalysts were characterized using the following analyses elemental analysis, total acid density, FT IR, SEM and XRD. Based on the above characterization results, sulfonated carbon prepared at 500 and sulfonated via ultra sonication was found to have a higher acid density that is suitable to catalyze the hydrolysis reaction. The first step in the catalyst development approach was to increase the hydrolysis reaction by employing a stronger sulfonation procedure during catalyst preparation. The total acid density obtained for sulfonated carbon catalyst at 500 was 4.16 mmol g which significantly increases glucose yield. According to the FTIR analysis the sulfonated bio char contained sulfonic, carboxylic, and phenolic groups, which are responsible for the exhibited high catalytic performance during hydrolysis of cellulose. The yield of glucose obtained was 60.5 at 149.0Â°C in 8hour reaction time.

Design and Analysis of Crane Hook with Different Materials

Cranes are industrial machines that are mainly used for materials movements in construction sites, production halls, assembly lines, storage areas, power stations and similar places. A hook is a tool consisting of a length of material that contains a portion that is curved or indented, so that this portion can be used to hold another object. In several uses, one end of the hook is pointed. They are used to transfer the materials having heavy loads. Crane hooks are liable components subjected to failure due to stress in accumulation of heavy loads. Area of cross section, material and radius of crane hook are the design parameters for crane hook. Failure of a crane hook mainly depends on three major factors i.e. dimension, material, overload. In this paper the design of the hook is done by analytical method and design is done for the different materials like forged steel and high tensile steel. After the analytical method design and modelling of hook is done in modelling software SOLIDWORKS . The modelling is done using the design calculation from the modelling the analysis of hook is done in FEA software ANSYS WORKBENCH . This result leads us to the determination of stress in existing model. By predicting the stress concentration area, the hook working life increase and reduce the failure stress.

Design and Analysis of High Performance Floating Point Arithmetic Unit

A floating point arithmetic unit designed to perform operations on floating point numbers as well as fixed point numbers. Floating point numbers can support a much wider range of values in comparison to fixed point representation. Floating Point units are mainly used in high speed objects recognition system, high performance computer systems, embedded systems and mobile applications. To represent very small values or very large values, large range is required as the integer representation is no longer appropriate to represent these numbers so these values can be represented by using floating point representation that is based on the IEEE 754 standard. The proposed floating point arithmetic unit is designed using single stage implementation. Due to single stage implementation the complex logic operations which consist of various multiple numbers of stages are converted into single stage implementation. So by using single stage implementation the time requires to reach data from input to output becomes less. The proposed unit is designed in VHDL, simulated in Questa Sim simulator and implemented on vertex 7 FPGA.

Comparison of RCC Buildings with a Soft Storey Irregularity in Different Zones

Soft storey is one of the main reasons for building damage during an earthquake and has been mentioned in all investigation report. Soft storeys in a high rise building play an important role on its seismic performance. At the soft storey level, there is a discontinuity in the rigidity of the structure due to lack of infill walls or due to variation in floor height. Soft storey is generally utilized as a part of auxiliary individuals in a building. Ex cellar stopping, shops. soft story is floor level in which the stiffness of the floor is under 80 of the normal stiffness of three stories above it. Earthquake occurred in multi storeyed building shows that if the structures are not well designed and constructed with an adequate strength it leads to the complete collapse of the structures. To ensure safety against seismic forces of multi storied building, there is need to study of seismic analysis to design earthquake resistance structures. Building irregularities generally become obvious with the effect of a seismic load. It is crucial that the irregularities of structural systems should be considered properly with respect to the conditions determined by the building codes.

Effect of Dimple Protrusion Shape on The Cooling Performance of The Turbine Blade Using CFD

It is well understood that one way to improve a gas turbine engines power output and thermodynamic performance is to increase the temperature of the turbine inlet TIT . The inlet temperature should be gradually elevated to higher targets to pursue greater control. However, with the rise in blade inlet temperature, the heat applied to the blade increases, and the permissible melting temperature of materials increases at a slower rate. This implies that the inlet temperature of the turbine blade will exceed the melting temperature of the material by more than 500 . Thus, cooling turbine blades for a safe and long lasting operation is important. To lower the temperature of the blade content below its melting point, different internal and external cooling techniques are employed. . In recent years, in the tip region of the turbine blade, multiple augmentation devices such as fins, ribs, pins, and dimples protrusions have gained a lot of attention to enhance heat transfer. With increasing inlet temperature of the turbine, pin fin arrays cannot satisfy the need of the cooling alone. To be paired with the pin fin arrays, several more methods are also added. With slight loss of pressure, dimples and protrusions are fine options. In this present work, the numerical approach is used to investigate the influence of dimples or protrusions shape on the cooling of the turbine blade. The ANSYS 17.0 simulation software was used. The results of this study show that the , due to flow acceleration, increase in impingement area and shrinkage of the flow recirculation region within the dimple, pin fin dimple wedge duct with triangular shape dimples protrusions provides improved heat transfer enhancement.

A Review Paper on Gas Turbine Blade Cooling Methods

For aircraft propulsion, land based power generation, and other industrial applications such as trains, marines, automobiles, etc., gas turbines are commonly used. The operating temperature must be raised to increase the thermal performance and output work of the gas turbine engine to accommodate the accelerated production of modern gas turbines. The heat transmitted to the turbine blade, however is greatly increased as the temperature of the turbine inlet is constantly increased. For a long service life and healthy running, it is also very important to cool the turbine blades. Currently available methods for cooling turbine blades include film cooling with impingement cooling for the front edge, turbulent rib cooling with serpentine passages for the middle section of the blade, and pin fin cooling for the trailing edge of the turbine blade. The cooling system for turbine blades must provide cooling for all potential regions that are subjected to hot gas flow. This paper provides a literature review of blade tip leakage and heat transfer, as well as studies into external and internal cooling technologies.
