Influence of Geometric Parameters on Intake Performance of 3D Ramp‐Type Scramjet Inlet
International Journal of Aerospace EngineeringThe methods based on the assumption of inviscid flow are typically used for the initial design of the scramjet inlet geometry, but the presence of a viscous boundary layer can degrade the validity of the results and lead to nonoptimal operation.

Kernel-based active subspaces with application to computational fluid dynamics parametric problems using the discontinuous Galerkin method. [PDF]
Int J Numer Methods Eng, 2022 Abstract Nonlinear extensions to the active subspaces method have brought remarkable results for dimension reduction in the parameter space and response surface design. We further develop a kernel‐based nonlinear method. In particular, we introduce it in a broader mathematical framework that contemplates also the reduction in parameter space of ...

Influence of plasma-enhanced combustion on RBCC engine using URANS [PDF]
Scientific ReportsThe rocket-based combined-cycle (RBCC) engine is regarded as one of the most viable propulsion systems for single-stage-to-orbit launch vehicles. Because of the relatively low total temperature of the incoming flow, it is difficult to maintain sustained ...
