MHD Oscillatory Free Convection Flow Past Parallel Plates with Periodic Temperature and Concentration

摘要

This communication investigates the effect of magnetic field on unsteady free convection oscillatory flow through vertical parallel porous flat plates, when free stream velocity, temperature and concentration oscillates in time about a non zero constant mean. The governing equations are solved by adopting complex variable notations. The analytical expression for velocity, temperature and concentration fields have been obtained using perturbation technique. The effect of various parameters on mean flow velocity, transient velocity, transient temperature, transient concentration, mean skin frication, amplitude and phase of skin-friction and heat transfer have been discussed and shown graphically.
