CFD Analysis Of Heat Transfer Using Counter Flow Single-Pass Shell And Tube Heat Exchanger.

Abstract

This study uses the CFD analysis program ANSYS fluent to investigate the heat transfer of a counter flow single pass Shell and Tube Heat Exchanger (problem statement). With the aid of ANSYS fluent, a simulation of conjugate heat transfer is performed. SolidWorks CAD software is utilized for the 3D design of the issue statement, and the geometry is added to ANSYS fluent CFD Solver to construct the boundary conditions to solve the problem. When the inlet temperatures are 15 °C and 90°C, and the fluid is flowing in the opposite direction, water is employed as the working fluid in the Tube and Shell fluid domain. To determine whether or not the heat transfer is improved, a simplified model of a counter-flow plain tube heat exchanger (Body of copper) is contrasted with the desired model of a heat exchanger, which has a (Body of steel) placed evenly along the length of the tube. Fluid outlet temperature is measured using the experimental data all during the CFD simulation. To support the increase in heat transfer, LMTD is also calculated and compared with a standard case or model. It is discovered from the experiment that the LMTDs of plain tubes with copper and steel bodies are 54.89°C and 55.25°C, respectively. Since, LMTD of the Copper and Steel body tube counter-flow heat exchanger is approximately same, So the finding is said that there is tiny difference between the body of those
