Abstract:
The time dependent Couette flow (CF) of a conducting fluid formed between two concentric tubes with variable electric potential and accelerated motion of the outer cylinder is investigated. The governing electric field potential as well as the momentum equivalences are gotten from Poisson-Boltzmann and Navier Stokes Eqs respectively. ; As a promising tool for solving time-dependent problems, the Laplace-transform technique is employed to get analytical solution for electric field and velocity profile in Laplace realm. By employing the Riemann sum approximation (RSA) simulation, the results are obtained numerically in time-domain. During the graphical and numerical simulation of obtained results, it is found that the magnitude of electrokinetic effect as well as Debye-Hückel parameter play important role in flow formation and mass flow rate in the horizontal annulus. ; Further, velocity, mass flow rate, and skin-friction decrease with increase in Debye-Hückel parameter at all-time regardless of the mode of application of magnetic field. In addition, mass flowrate can be enhanced with increasing Hartmann number when the magnetic-field is fixed relative to the moving cylinder.
