| description | This paper considers
the numerical optimization of a double ramp
scramjet inlet using magnetohydrodynamic (MHD)
effects together with inlet ramp angle changes.
The parameter being optimized is the mass
capture at the throat of the inlet, such that
spillage effects for less than design Mach
numbers are reduced. The control parameters for
the optimization include the MHD effects in
conjunction with ramp angle changes. To enhance
the MHD effects different ionization scenarios
depending upon the alignment of the magnetic
field are considered. The flow solution is based
on the Advection Upstream Splitting Method
(AUSM) that accounts for the MHD source terms as
well. A numerical
Broyden-Flecher-Goldfarb-Shanno- (BFGS-) based
procedure is utilized to optimize the inlet mass
capture. Numerical validation results compared
to published results in the literature as well
as the outcome of the optimization procedure are
summarized to illustrate the efficacy of the
approach. |
