Design and simulation of Shell-and-Tube Heat Exchanger (STHE) with the effect of Baffles using CFD-tool
Downloads
In the current scenario, heat exchangers are used in the thermal system to maintain the working liquid's temperature. Due to their robust design and performance characteristics, the Shell and Tube Heat Exchangers (STHE) are mainly used in the generation of electricity, the cooling of hydraulic fluid, transmissions, and hydraulic power packs. This can further be improved to achieve a higher heat transfer rate. It consists of a casing with several tubes inside. The project’s ideology is based on the use of baffles attached to the heat exchanger to increase the flow rate of highly viscous fluids. The paper’s intended result is to determine the rate of heat transfer using hot water as the hot liquid. The theoretical analysis results obtained in this study were reasonably predicted by computational fluid dynamic (CFD) under Ansys Cfx. The simulation consists of modeling, meshing cross-sectioning, and the fluid behavior in the shell and tube of STHE are used in Ansys fluent 16.0. Finally, the effectiveness of the design parameters and contour conditions published under Ansys Cfx.
