Abstract: This paper deals with the concentric tube heat exchangers which are made of galvanized iron and copper materials. In this paper, three different L/D ratios (157.89mm, 98.91mm, 63.33mm) were considered for analyzing the parallel and the counter flow processes. ANSYS FLUENT software 14.5 is used to find the theoretical calculations and also to study the inlet temperature, velocity & pressure drops. These calculations are helpful to validate the efficiency of the concentric pipe heat exchanger and also to know how these values vary with each other. Computational Fluid Dynamics is used to asset the outlet temperature of both the counter and parallel flow heat exchangers. Finally the results were analyzed between both counter and parallel flow heat exchangers in order to identify the most efficient one.
