Overview of piv in supersonic flows
WebThe method for estimating time-resolved three-dimensional velocity field is developed to investigate the high spatial and temporal flow structures of the supersonic jet with the Mach number of 1.35. The supersonic jet were measured by non-time-resolved particle image velocimetry (PIV) measurement and time-resolved near-field acoustic measurement. WebAbstract. Hydrodynamic simulations of granular convection predict the existence of supersonic flows covering ∼ similar-to \sim ∼ 3-4% of the solar surface at any time, but …
