ANALYTICAL SOLUTION FOR THE TEMPERATURE DISTRIBUTION IN CROSS-FLOW PLATE HEAT EXCHANGER CHANNELS OF ISOSCELES TRIANGULAR GEOMETRY

This paper presents the analytical solutions for the temperature distribution in cross-flow plate heat exchanger under uniform temperature boundary conditions. The heat transfer channel is in a form of an isosceles triangular geometry. The governing equations are based on the conservation of energy principle. The mathematical models, for both unmixed fluid, are solved by Laplace Transform leads to the developed analytical solution that is in the form of modified Bessel function of the first kind and zero order
