A numerical investigation of geometry effects on the flow characteristics associated with converging-diverging 2D planar micronozzles is reported. The classical N–S with linear slip …
We perform a combined numerical and experimental study to investigate the transonic shock- wave/turbulent-boundary-layer interactions (STBLI) in a shock-induced separated subscale …
