Abstract


MHD Flow Over a Moving Infinite Vertical Porous Plate With Uniform Heat Flux In The Presence Of Thermal Radiation With reference to all critical parameters that appear in the field equations were was studied in this paper. In most of the literature, the flow parameters were neither examined nor commented in detail in any of the above investigators. This is a point of great concern and is if academic interest to study. Also, not much of prime importance was given to the bounding surface and factors influencing the skin friction. Therefore, an attempt has been made to study the influence of such critical parameters that appear in the field equations and their effects on various flow entities. It is noticed that as the frequency of excitation decreases the velocity decreases. Further, as we move away from the boundary of the surface the velocity decreases. The effect of the frequency of excitation and for a constant pore size has been illustrated. In this case, it is noticed that as the frequency of excitation decreases the velocity decreases. Further, as we move away from the boundary of the surface the velocity decreases. it is reported that, as the frequency of excitation decreases the velocity also decreases. In addition to the above, as we move far away from the boundary of the surface the velocity decreases. Also, it is has been reported that, as the pore size of the boundary surface decreases, the velocity also decreases. Further, as we away from the bounding surface the velocity decreases.  For different values frequency of excitation, the profiles of skin friction are noticed to be linear and of course with negative slope. It is noticed that as the frequency of excitation decreases, the skin friction on boundary surface found to be increasing.
