DOI: 10.1007/s00348-020-03009-2
Abstract: There is a dearth of information on the reflection of very weak shock waves on curved surfaces; and particularly a distinct lack of experimental data at Mach numbers below 1.03. A previous study at Mach… read more here.

DOI: 10.1016/j.jsv.2017.01.030
Abstract: Abstract The use of unsteady incompressible-flow simulations has become very popular for aeroacoustic noise predictions at low Mach numbers, as it provides a good compromise between computational time and reliable predictions. The acoustic radiation of… read more here.

DOI: 10.1063/5.0022015
Abstract: The experimental analysis of base pressure in a high-speed compressible flow is carried out. The flow is made to expand abruptly from the nozzle into an enlarged duct at fifteen sonic and supersonic Mach numbers.… read more here.

Abstract: A discrete-velocity Boltzmann equation (DVBE) with Bhatnagar-Gross-Krook (BGK) approximation is discretized in time and space using a third-order Runge-Kutta (RK3) and fifth-order weighted essentially nonoscillatory (WENO) finite-difference scheme to simulate benchmark inviscid compressible flows. The implementation… read more here.
