Abstract

Flow over rotating cylinders is very important in a wide number of applications from shafts and axles to spinning projectiles. This can sustain lives or put lives at serious risk which may lead to death sometimes. That is why this work investigates unsteady reactive flow of rotating concentric cylinder (annulus) with reactive term with both cylinders rotating in opposite direction. The cylinder’s length is finite and the reactive proximity is fixed to be 0.50mm, considering the effect of pressure gradient (G) on magnetic field on other parameters. The governing equations on reactive flow in a rotating concentric cylinder were derived. Guided by related journal’s results on reactive flow in a rotating concentric cylinder which are applicable to moving machine systems. The incompressible with constant density governing equation were used to investigate the impacts of magnetic force, pressure gradient, 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. The unsteady and one-dimensional equations and axial symmetric flow of the Newtonian fluid in the rotating concentric cylinder with fixed proximity and boundary conditions were investigated. Finite difference method with MAPLE 2014 software, was used for the interpretation of figures and the results were in agreement with the reviewed journal.
