least square method for porous fin in the presence of uniform magnetic field

In this study, the least square method (lsm) is a powerful and easy to use analytic tool for predicting the temperature distribution in a porous fin which is exposed to uniform magnetic field. the heat transfer through porous media is simulated using passage velocity from the darcy’s model. it has been attempted to show the capabilities and widerange applications of the lsm in comparison with a type of numerical analysis as boundary value problem (bvp) in solving this problem. the results reveal that the present method is very effective and convenient, and it is suggested that lsm can be found widely applications in engineering and physics.
