Performance simulation of a double pipe heat exchanger using MATLAB

Abstract

Heat Exchangers are primarily used for transfer the heat. Design of heat exchanger is one of the key factor compact devices. The requirement of heat exchanger rate is low, suitable applications are Refrigeration, air condition, Boiler and space heating etc. The Design consist of Concentric pipes where the hot oil will pass in the annular Region and the sea water will pass through the inner pipe. Flexibility is achieved in the design about parallel flow and counter flow depending on selection of inlet and outlet of annular fluid. This Heat Exchanger in intended to be installed in a sea vessel to reduce the temperature of the oil used to cooled engine. Different Governing Equations and empirical relations are used for the designation. Simulation was done by MATLAB software. Copper is Selected for inner tube and outer tube we used iron pipe. 1” copper tube used for inner tube and 2” Iron used for outer tube.
