Description
Summary:In this mathematical model, influence of EHD as well as permeability and radiation were added to find the ferrofluid treatment. Radiation term was involved in temperature equation while other terms have been added in flow equations. To simplify the mathematical model, vorticity formulations were utilized and CVFEM was applied to reach the solution. Low concentration of iron oxide lets to reach properties of operating fluid from empirical formulations. Outcomes were summarized in view of plots and contours to illustrate the influences of Da, Voltage and radiation parameters as well as shape factor. Augmentin of Rd causes Nu to augment about 82.27%. Better mixing can be achieved with rise of Da and Nu enhances about 36.91%. Impose of EHD provides external force which helps the convective flow and stronger thermal plume will be generated. With apply of Coulomb force, Nu augments about 23.96% and 83.96% when Da = 10 2 and 10 5 , respectively.
