DOI: 10.1016/j.actaastro.2021.02.030
Abstract: Abstract In this paper, supersonic unsteady flows around the spiked cylinder are investigated through two-dimensional (2D) and three-dimensional (3D) unsteady Reynolds-averaged Navier–Stokes (URANS) approaches. Three types of spikes are used to provoke pulsating/oscillating flow in… read more here.
