International Journal for Numerical Methods in Engineering, Volume 123, Issue 23, Page 6000-6027, 15 December 2022., 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 the Multicavity Shape on the Solid Scramjet
International Journal of Aerospace Engineering, 2021 In this paper, a modular solid scramjet combustor with multicavity was proposed. The influence of multicavity shape on the performance of solid scramjet was investigated by the direct-connected tests. The experiments simulated a flight Mach 5.5 at 25 km.
