Abstract:- A three dimensional numerical study has been conducted on finned-tube heat exchanger with multiple rows of tubes using ANSYS (Fluent). The objective of this study is to numerically investigate finned tube heat exchanger with different type of tubes such as circular, elliptical and rectangular tubes. As circular
Shell and tube heat exchanger (STHE) has its own importance in the process industries. Methods Experimental and numerical simulations are carried for a single shell and multiple pass heat Numerical study of shell and tube heat exchanger with Feb 12, 2019 · Shell and tube heat exchangers are used in various industrial processes, and are one of the most commonly used heat exchangers. A shell and tube heat exchanger with a 25% baffle cut was used in this study. Tubes of different cross-sections (circular, elliptical with an attack angle of 90° and elliptical with an attack angle of 0°) were studied.
A theoretical model for predicting the performance of a shell and tube heat exchanger using elliptical tubing and validating the predictions are done. The shell is cylindrical shape with a circular cross section. The E shell is most common due to its low cost and simplicity. Design of tube has been carried out in STHEx to predict the Numerical and heat transfer analysis of shell and tube The shell and tube heat exchanger with circular tubes and 60° tube orientation for baffle using 25 % cut was taken as an experimental device. The dimensions of the STHE are shown in Fig. 1. The shell is made of stainless steel, and the tube is made of copper. The circulated hot fluid was used in the tubes and the cold fluid in the shell.
