EXPERIMENTAL ANALYSIS AND SIMULATION OF DOUBLE PIPE HEAT EXCHANGER

MECHANICAL ENGINEERING

Heat transfer simulation techniques refer to analyzing the heat exchangers overall performance by using simulation software’s such as ANSYS, CFD Analysis, etc. Mainly these techniques are used for analyzing the various parameters of the heat exchanger and the comparison is done with the computational fluid dynamics and experimental results. The applications of heat exchanger are in Thermal Power Plants, Process Industries, Refrigerators, Air Conditioning Equipment, Automobiles, and Radars for Space Vehicles etc. In the last decade several studies on the on the CFD techniques of heat exchangers have successfully done by researchers. The present paper review mainly focuses on the heat transfer enhancement by checking it with ANSYS FLUENT 16.0 by using various types of flow and using twisted tape and without using twisted tape. By doing the CFD of the double pipe heat exchanger with various boundary conditions and various flow parameters the results are obtained and compared with computational fluid dynamics and experimental validation to know the actual variation of different parameters. Thus it would cause to select the appropriate heat exchanger; actual comparison can be done and compared. Actual parameters are found using the simulation techniques and the actual values are determined of the parameters such as Nusselt number, Effectiveness of the heat exchanger, overall heat transfer coefficient etc.
