WebIn a counter flow cooling, the incoming cooling medium absorbs heat as the ‘hot’ fluid travels in the opposite direction. The cooling medium heats up as it travels through the … WebCFD study of helically coiled double pipe heat exchangers for laminar flow situations were carried out by Rennie and Raghavan (2005, 2006a) . They have modelled the heat transfer from hot fluid to cold fluid using the CFD pa ckage PHOENICS 3.3 and found out the overall heat transfer coefficients for counter current and parallel flows.
WebAug 9, 2024 · Counter flow heat exchangers are inherently more efficient than parallel flow heat exchangers because they create a more uniform temperature difference between the fluids, over the entire length of the fluid path. Counter flow heat exchangers can allow the "cold" fluid to exit with a higher temperature than the exiting "hot" fluid. WebMar 3, 2024 · Counter Flow Double Pipe Heat Exchangers. The best design for a double pipe heat exchangers is counter flow. In this pattern, the heat exchanger has the optimum heat transfer coefficient and can cold or heat the outlets as we desire. Figure 2 illustrates the position of the inlets and outlets. As it is shown in this type, the flows flow in the ...
