In addition to 25 % baffle cut, quarter baffle cut and mirror quarter baffle cut arrangements are used for comparison. Both circular and elliptical tube geometries with 450,600 and 900 orientations are used for the numerical studies. Fluent software is used for numerical investigations. Heat transfer rates and pressure drops are calculated for various Reynolds numbers from 4000 to 20000. The experiment was carried out with hot fluid in tube side and cold fluid in shell side with circular tubes at 600 tube orientation and 25 % baffle cut. MethodsĮxperimental and numerical simulations are carried for a single shell and multiple pass heat exchangers with different tube geometries i.e. Shell and tube heat exchanger (STHE) has its own importance in the process industries. Various heat exchangers are designed for different industrial processes and applications. Heat exchanger is a device in many industrial applications and energy conversion systems.
