Oblique wave interactions in 2D steady supersonic flows of Bethe-Zel'dovich-Thompson fluids
Geng Lai
This paper studies steady supersonic flow in a 2D semi-infinite divergent duct. We assume that the flow satisfies the slip boundary condition on the walls of the duct, and the stat…

Two-dimensional steady supersonic ramp flows of Bethe-Zel'dovich-Thompson fluids
Geng Lai
Two-dimensional (2D) steady supersonic ramp flows are important and well-studied flow patterns in aerodynamics. In the paper [41], Vimercati, Kluwick, and Guardone constructed vari…

On the expansion of a wedge of van der Waals gas into vacuum III: interaction of fan-shock-fan composite waves
Geng Lai
This paper studies the expansion into vacuum of a wedge of gas at rest. This problem catches several important classes of wave interactions in the context of 2D Riemann problems. W…
