“…As discussed in Lindsey et al [13] and Van Wie and Nedungadi [21], and especially, the arguments presented in some details in Shenider et al [22], two criteria can be allocated for the parameters, namely, In what follows further, the roles played by those parameters in the MHD controlled inlet at off-design conditions through numerical simulation are investigated.…”

“…[12] According to the AJAX program, the inlet control can be furnished by an MHD device through the modification of the external flow upstream of the scramjet inlet to provide improvement on the engine performance at off-design conditions. Lindsey et al [13] studied the MHD flow control within the internal inlet of a full scale. They found that the placement of the electromagnetic interaction region near the wall was the most important factor in determining the wall heat transfer and limiting drag increases.…”

The purpose of this study is to perform numerical simulation for the design and optimization of three-dimensional magnetohydrodynamic (MHD) controlled hypersonic inlets. An airframe/propulsion integrated module was first established for a waverider-based hypersonic vehicle at design Mach number of 6. Using this generic configuration, an MHDbased technique for large-scale inlet flow control is studied at the off-designed Mach value of 8.5. The results indicate that the inlet mass flowrate can act as an optimization criterion. Using a proper value of mass flowrate, an MHD generator possessing reasonable design parameters can effectively restore the flow field shock structure, i.e. shock-on-lip condition and improves the flow field characteristics at the combustor entrance at higher Mach number than the design value. The results further reveal that the MHD effect on the flow with higher load factor helps to extract more electric power from the external MHD generator and also helps in improving the performance of the combustor entrance.
