A Review on Study of Heat Transfer Analysis of Helical Coil Heat Exchangers

Now a day’s a geometrically modified Helical coil heat exchangers are widely using in industrial applications like cryogenic state processes, air conditioning, thermal nuclear reactors and waste heat recovery due to their compact size and high heat transfer coefficient. Advantage of using helical coils over straight tubes is that the residence time spread is reduced, allowing helical coils to be used to reduce axial dispersion in tubular reactors. In this study, numerical investigation of the influence of geometrical parameters such as tube diameter d , coil radius R , and coil pitch p on overall heat transfer coefficient in helical double tube heat exchangers are performed using a professional CFD software FLUENT. In recent years, numerous styles were introduced for heat exchangers that apply to completely different applications sadly, their heat transfer co efficient wasnt reliable at different operational conditions. the standard of the heat changed rate wasnt optimized and there have been many deficiencies and errors in styles. The heat transfer of the copper material is enhanced in comparison with other material unfortunately thermal resistance is reduced with an increase in pressure drop thus enhancing the heat transfer on the heat exchanger. Helical architecture is often designed with a clear motive of compact size and also address heat transfer co efficient and other ancillary attributes efficiently and effectively. So the better material is suggested for an industrial heat exchanger according to the applications is Copper with the basis of simulation results. The geometry and different dimension parameter of the helical coil show that the proposed study in different material properties and different mass flow rates to heat transfer are maximum in different parameter helical coil heat exchangers. Finally, the heat transfer increase for the copper material compared to another material but with the increase in pressure drop the corresponding thermal resistance decreases which allow the improved heat transfer rate and the rate increases from Aluminum to Bronze to Copper. With the drop in temperature, the thermal resistance is reduced which enhances the heat transfer rate. The simulation results show that the copper has a high heat transfer coefficient than Aluminum and Bronze while operating in identical conditions. Due to the extensive use of helical coils in various applications, knowledge about the flow patterns and heat transfer characteristics are important.

Workability Performance of Fresh Concrete Incorporated with GSA, GGBS and WF

The concrete is the most widely used building materials in the world throughout for the construction of infrastructure and other structures. The concrete is the second widely used substance on the earth next to water. The concrete is the composite homogeneous materials, which is commonly consists of cement, fine aggregate, coarse aggregate and water. Among the various materials, the cement is most important materials in the preparation concrete. It will provide bond strength to concrete by binding the fine and coarse aggregate with each other due to chemical reaction developed by hydration of water. At the same time, the cost of cement is very high when compared to other materials used in concrete. On the other hand, the manufacturing of cement in large quantity is producing environmental pollution by emitting the CO2 content in huge volume to the environment. These two issues are induced the Civil Engineers to find the alternative binding materials for the better replacement of cement. In this research work, the locally available agricultural and industrial waste materials are used for the partial replacement of cement. In this present study, the agricultural waste used is Groundnut Shell Ash GSA and industrial waste material is Ground Granulated Blast furnace Slag GGBS . The GSA is an ash obtained after burning the groundnut shell at high temperature in the kiln and the GGBS is a non metallic waste material available from iron industry. Hence the utilization of these waste materials without a harmful effect on nature has an important role for the manufacturing of concrete in conduction industries. In the present work, it is proposed to examine the workability performance study of concrete with partially replacing the cement with GSA, GGBS and WF with and without addition of super plasticizer. The slump test and compaction factor test were performed to evaluate the workability characteristics of fresh concrete for M20 mix grade.

Dynamic Study of Parabolic Cylindrical Shell A Parametric Study

The shell structures are composed of a thin shell made of reinforced concrete without the use of interior columns giving an open on the inside. Most general shells used in manufacturing industries are flat plates and domes but different shapes like cylindrical, parabolic or spherical section may also used. Storage facilities and Games arena buildings are common concrete shell structures. On the other hand, they can be complicated to design, as the exact shape necessary for stability of structure depends on the material used, the size of the shell, exterior or interior loading, and other oblique. So by varying the parameter of the shell, performance of the shell is also varying. Main objective of this paper is parametric analysis of the various cylindrical shell structures with different lengths. For analysis we took two different lengths of cylindrical shell and then, two parameters have been vary first one is radius and second is thickness, on the basis of different radius and thickness for same chord width, length, and material of shell we will evaluate the behaviour of shell for different models.

Importance of Basic Principles of Design in Creating Spaces

Organization is the essence of any design and doing nothing is also a form of design. When it is an applied design, it is hazardous to design by neglect and default. Design sometimes suffers from a dilemma about its identity. It is not solely either an art or a science but is a combination of both. Applied design is not like physics or biology or writing or painting, but it involves these areas and more. Design tends towards a generalized approach, collecting specifics from diverse areas as needed. Design is a combination of art, science, technology and intuition. Basic Design does contain sound proven principals and criteria for judging its success. These criteria centre on the relationship between human needs and human environmental possible with very basic elements used to derive solutions and paces as per human comfort. The measure of the success of a particular applied design is how well it meets the needs of the people experiencing it. Basic principles are mandatory to be learned, understood and used wisely to make the best contribution the process of Designing. This paper is an attempt to focus on explaining design with point, line plane and Volume.

Development of Neuro Fuzzy Based Temperature Control for Egg Hatchery

Neuro fuzzy have been successfully applied to extract knowledge from data in the form of fuzzy rules. This project describes the development of Adaptive Neuro fuzzy system applied to the temperature variable of a thermal system with a range of 35 to 40Â°C for Egg Hatchery control. The system developed was based on heat transfer based on the principle of radiation to actualize the system. The generation of membership function is a challenging problem for fuzzy systems and the response of fuzzy systems depends mainly on the membership functions. The ANFIS based input output model is used to tune the membership functions in neuro fuzzy system. Experimental results were determiner. Processing the membership function the ANFIS was trained, tested and validated. The neuro fuzzy controller used the neural network learning techniques to tune the membership functions while keeping the semantics of the fuzzy logic controller intact. Both the architecture and the learning algorithm are presented for a general neuro fuzzy controller. In conclusion, a resulting effective system temperature control with energy conservation up to 100 eggs was achieved. The developed system finds application in egg incubation system industry.
