Abstract: In the present work, the dimension of shell and tube heat exchanger has been optimized. After reviewing different types of inserts, its advantages and disadvantages method of manufacturing, it was decided to study the center rod wire coil inserts, which appears to be most efficient than others. Both analytical analysis and CFD simulation has been done. Model was made on SolidWorks software and imported in ANSYS 14.5. In ANSYS 14.5, Fluent is used as a solver. The result shows that performance of shell and tube heat exchanger was increased with insert and further the dimension has been optimized. The overall heat transfer increased by 182 % in analytical analysis and by 199 % in CFD simulation results. The length of shell and tube heat exchanger was reduced from 1000mm to 360mm and number of baffle also minimized from 15 to 06. The TEMA standard is also considered for design heat exchanger. Based on obtained results, the results are compared.
