The Double Pipe Heat Exchanger in counter flow configuration consists of one fluids flow from the inner pipe while the other flows in the opposite direction from the outer pipe. This project analyzed and designed this heat exchanger utilizing numerical simulation in ANSYS and facilitated optimization by performing a change in the inner tube material. Based on the second simulation analysis the minimum percentage difference was reduced from 2.70% to 0.70%. When changing the inner tube material to copper and maintaining the same initials conditions a 12.07 K decrease in temperature difference was achieved for the hot water. It is found that the visualization of the distribution of the temperature and pressure that numerical simulation provides, gives a better understanding of the heat exchanger and having the system model in ANSYS useful for optimization.
