“…In recent years, more and more work about MHD-controlled boundary layer has been studied experimentally [4][5][6][7] and numerically [8,9]. In [8], the effects of load parameter and magnetic interaction parameter on hypersonic corner SWBLI flow has been investigated extensively.…”

“…A range of recent experiments and simulations have been carried out on the supersonic boundary layer and separation control using MHD plasma actuators. In some examples, Meyer et al (2004), Zaidi et al (2006), and Saito et al (2008) conducted MHD boundary layer control experiments in wind tunnels at Mach 3, Mach 2.8, and Mach 1.5. Experimental results showed that MHD had the effect of increasing the momentum and attenuating the density fluctuations of the boundary layer.…”

The effect of magnetohydrodynamic (MHD) plasma actuators on the control of hypersonic shock wave/turbulent boundary layer interactions is investigated here using Reynolds-averaged Navier-Stokes calculations with low magnetic Reynolds number approximation. A Mach 5 oblique shock/turbulent boundary layer interaction was adopted as the basic configuration in this numerical study in order to assess the effects of flow control using different combinations of magnetic field and plasma. Results show that just the thermal effect of plasma under experimental actuator parameters has no significant impact on the flow field and can therefore be neglected. On the basis of the relative position of control area and separation point, MHD control can be divided into four types and so effects and mechanisms might be different. Amongst these, D-type control leads to the largest reduction in separation length using magnetically-accelerated plasma inside an isobaric dead-air region. A novel parameter for predicting the shock wave/turbulent boundary layer interaction control based on Lorentz force acceleration is then proposed and the controllability of MHD plasma actuators under different MHD interaction parameters is studied. The results of this study will be insightful for the further design of MHD control in hypersonic vehicle inlets.

“…The increasing interest in the study of MHD phenomena is also related to the development of fusion reactors where plasma is confined by a strong magnetic field [6]. Many exciting innovations were put forth in the areas of MHD propulsion [7], remote energy deposition for drag reduction [8], MHD control of flow and heat transfer in the boundary layer [9,10].…”

In this paper, the steady flow and heat transfer of an incompressible electrically conducting micropolar fluid through a parallel plate channel is investigated. The upper and lower plate have been kept at the two constant different temperatures and the plates are electrically insulated. The applied magnetic field is perpendicular to the flow, while the Reynolds number is significantly lower than one i.e. the considered problem is in induction-less approximation. The general equations that describe the discussed problem under the adopted assumptions are reduced to ordinary differential equations and closed-form solutions are obtained. The influences of each of the governing parameters on velocity, heat transfer on the plates (Nusselt number), flow rate and skin friction are discussed with the aid of graphs.
