Abstract

The uneven road and overloading of moving vehicles and machines seems to be the major problems facing the reactive flow in rotating concentric cylinder in moving vehicles and machines. That is why this work investigates unsteady reactive flow of rotating concentric cylinder with reactive term having both cylinders rotating in opposite directions. The cylinders proximity is fixed to be 0.50mm, the magnetic field was investigated on other parameters in the governing equations. The governing equations were derived and Hartmann number (Ha) and some other parameters, were investigated guided by related journal's results. The governing equation were used to investigate the impacts of magnetic force on porosity, thermal conductivity, heat dissipation potential, velocity, temperature and the flow rate of the fluids in the rotating concentric cylinder (annulus). The energy equations were formulated with reactive term for proper results justification. Finite difference method were used to generate the solutions of both momentum and energy equations. MAPLE 18 software were used for the interpretation of figures and results. The velocity profile for values of Darcy number (Da) from 0.00mms' to 2.00mms when the Ha is zero (0) it shows that the velocity is not smooth and as the Ha increases; velocity also increases. When all the parameters are visible then the Ha becomes curve which indicated proper fluid flow. The higher the Ha the more the fluid flow within the proximity. The temperature of all parameter increases as Ha increases. Excellent results were achieved during the research period.
