ANALYSIS OF A TWO DIMENSIONAL RECTANGULAR FIN USING NUMERICAL METHOD AND VALIDATING WITH ANSYS

The two dimensional fin is analysed by numerical methods and validating with ANSYS by taking same boundary conditions and same grid size by taking certain assumptions. There are many mathematical techniques are available for finding the temperature distribution on fin surface [1][2]. But it contains higher order partial differential equation. So it is difficult to solve the equation. Numerical techniques convert the partial differential equation in linear algebraic equation which is easy to generate a program in MATLAB. Due to unavailability of actual practical set up we are taking ANSYS analysis is a base. For two dimensional problem even finite differences method is quite difficult to give the temperature distribution. But numerical method is comparatively easy and increases accuracy by taking more number of iteration or even number of grid because of availability of programming software.
