Under low heat duty conditions, double pipe heat exchangers are employed. When utilized for heavy-duty tasks, they show limitations. To use double pipe heat exchangers for heavy-duty applications, heat transmission needs to be increased. In this project, we are investigating the optimization process parameters of a twin pipe heat exchanger with and without protruding surfaces. In both cases, the inner and outer tubes are composed of steel, and the working fluid is water. Our goal is to increase the efficiency of the twin pipe heat exchanger, even if there are other configurations that may transfer the necessary quantity of heat. Optimal sizes where one of the process fluids is present can be calculated from the initial conditions. After comparing the outcomes of the two situations, we can choose the most effective model. The results of the investigation demonstrate that heat transfer rate values increase in tandem with flow rate values. We utilized the same number of boundary conditions and protruded the pipes to enhance the object’s performance. Our calculations revealed that the heat transfer rate values were much higher than those of a typical double-pipe heat exchanger, with the cold domain heat transfer values increasing by nearly three times and the hot domain heat transfer rate values increasing by roughly five to six times. This suggests that the performance of the object in terms of heat transfer values can be enhanced by the addition of protrusions.

Keywords: Double pipe heat exchanger (DPHE), double pipe with protrusion heat exchanger, coefficient of heat transfer, length and diameter, heat transfer rate
