CFD Analysis of Shall and Twisting Tube Heat Exchanger

Abstract

In this research, a heat exchanger was designed and analyzed using ANSYS software. Three heat exchangers were designed:1-shall and regular tube heat exchanger ,2- shall and square cross-section twisting tube heat exchanger and 3- shall and circular cross-section twisting tube heat exchanger. The metal used in manufacturing the shall and tube is copper. It was observed that the external surface of shall is no heat take place through its. Air was used as a fluid in heat exchanger, with cold air flowing inside the tube and hot air flowing inside the shall. The counter flow inside heat exchanger. Both fluids had 1m/s velocity at the inlet suction .It was result that the temperature of the air coming out of the circular tube is colder compared to a regular tube . Additionally, in the shall and square-cross section twisting tube heat exchanger, the pressure was higher at outlet compared to regular tube.
