“…It is shown that the shock-wave angle increases with the magnetic field strength and depicts a nonlinear variation. The analytical value 33 of the shockwave angle for the condition of zero magnetic field strength have a very good quantitative agreement with the data of the present simulation result, and the maximum deviation between the two data is less than 0.1%. Moreover, the shock-wave angle with the magnetic field strength of 1.0 T increases by about 13% compared to the one without the magnetic field.…”

The effects of external magnetic fields on the shock-wave configuration at hypersonic plasma flow field are investigated in this paper. A series of numerical simulations over various geometry configurations, namely, a blunt body and a fixed-geometry inlet forebody, have been conducted by varying the applied magnetic field under different freestream conditions. Results show that magnetohydrodynamic shock control capabilities under three types of magnetic field are ranked from weak to strong as dipole magnet, solenoid magnet, and uniform magnet field. Under the same applied magnetic field, it is easier to deflect the shock at a relatively high altitude condition, compared with the low altitude case. The bow shock standoff distance is dependent on the distribution of counter-flow Lorentz force right after shock in the stagnation region. For the oblique shock control, the function of two components of Lorentz force is different that the counter-flow one decelerates the flow and increases the shock-wave angle, while the normal one squeezes the oblique shock and deflects the streamlines.

“…In the past 20 years, magnetic control technology has been supplemented by experiments and simulations, and the research on magnetic control technology has also expanded to other aspects. The research contents include magnetic interaction model (Lineberry et al 2002, Bityurin et al 2004a, Shneider and Macheret 2005, Bityurin and Bocharov 2006, Nagata et al 2013, magnetic field type (Li et al 2017a, Yao et al 2018, re-entry orbit (Shimosawa andFujino 2016, Fujino andTakahashi 2022), simulation (Poggie and Gaitonde 2002, Fujino et al 2003, Bityurin et al 2005, Katsurayama et al 2008, Shimosawa and Fujino 2016, Li et al 2017b, experiment (Bityurin et al 2004b, Smith et al 2018, Lefevre et al 2021 and concept (Bisek et al 2013, Balasubramanian et al 2016.

The study of plasma flow under the thermal protection magnetic field of reentry vehicle is helpful to verify the magnetic control thermal protection technology and further understand its flow law. By solving hypersonic magnetohydrodynamics equations and combining with dipole magnetic field conditions, the plasma flow mechanism of RAM-CII (Radio Attenuation Measurement Experiment) spacecraft at 61km altitude is analyzed and compared with OREX (Orbital Reentry Experiment) spacecraft under the same conditions. The results show that the plasma flow of RAM-CII is more complex than that of OREX, and there are several regions with different Lorentz force directions near the aircraft, which play the role of plasma ejection and adsorption. Under the action of Lorentz force, the side flow of the aircraft will be separated and reattached, and the fluid stagnation zone will be generated. The results show that for different shapes of aircraft, the flow laws caused by magnetic thermal protection technology are different, and the side flow may be greatly affected.

“…In addition, the cathode voltage fall is too low to have obvious effects on MHD power generation. Balasubramanian et al (2016), had computationally studied the MHD power generation for controlling and augmenting the hypersonic flow, as well as for thermal management schemes, using a CERANS-MHD code. The concept was conceived to use the existing adverse hypersonic environment around the vehicle toward its advantage.…”

This document presents the results of an investigation of the impact of variations of electrical conductivity and magnetic field strength on the velocity profile inside a rectangular duct, assuming equilibrium flow. It also presents the physics and the complete theory associated with the MHD, then derive the equations to be utilized for computational analysis of the magnetic field and the velocity profiles.The computational work in this document is based on the assumption that the working fluid is air and it is fully developed in the duct. The finite difference method is used to perform the analysis for 2 distinct cases: the first case is when the magnetic field strength changes, while holding the electrical conductivity constant. The second case is when the electrical conductivity is changing while holding the magnetic field strength constant.It has been found that increasing the magnetic field strength has resulted in decreasing the axial velocity profile, which demonstrated that the magnetic field was pulling the flow to its direction, reducing the flow momentum in the axial direction. It has also been found that the electrical conductivity reduced the velocity profile in the axial direction when that conductivity was increasing, demonstrating that the electric field was also pulling the flow in its direction, reducing the flow momentum in the axial direction.
