Effects of Electrification and Transverse Force on Dusty Flow over a Linear Stretching Sheet

Abstract

The numerical investigation of the flow and heat transfer of steady dusty flow over a linear stretching sheet has been carried out. The effects of Transverse force and electrification has been incorporated in this problem. Modelling of the problem comprises of highly nonlinear partial differential equations that have been transferred to systems of ordinary differential equations by implementing suitable transformations. Since the equations are of boundary value problems in nature, have been transferred to initial value problem by using shooting method and then solved by RungeKutta 4th order technique. All the above numerical methods incorporated in the BVP4C tool of MATLAB and has been solved the systems of differential equations by using MATLAB software. The effects of different parameter like Prandtl number, Eckert number, transverse force, and electrification parameter on flow and heat transfer profile has been presented through graphs and tables. The results have been validated with previous authors. From the graph it is observed that the transverse force reduces the velocity of the particle phase in the flow where as electrification of particles raises the temperature of particle phase in the flow. The computations carried out with tolerance of order less than O (10^(-6) ).
