Physics of Fluids, Volume 35, Issue 4, April 2023. We examined the effect of hydrogen (H2) enrichment on the primary fuel methane (CH4) in a canonical non-premixed bluff-body stabilized burner operating under typical central jet-dominated flame mode. I…
Physics of Fluids, Volume 35, Issue 4, April 2023. In this study, a two-dimensional numerical simulation is conducted to investigate the characteristics of gas flow induced by an electrohydrodynamic (EHD) pump with needle-ring-net electrodes. A needle …
Physics of Fluids, Volume 35, Issue 4, April 2023. The complete Riemann solutions for the drift-flux model with the pressure law given both for the extended Chaplygin gas and also for the Chaplygin gas are solved in fully explicit forms. By the Chaplyg…
Physics of Fluids, Volume 35, Issue 4, April 2023. Skin-friction drag reduction by axial oscillations of an inner cylinder is numerically investigated at radius ratio (η = 0.5) using direct numerical simulation. In the present study, at fixed optimal o…
Physics of Fluids, Volume 35, Issue 4, April 2023. Large-eddy simulations are reported on a system consisting of a marine propeller and a downstream, semi-infinite hydrofoil, carried out on a cylindrical grid of about 3.8 × 109 points. The results are …
Physics of Fluids, Volume 35, Issue 4, April 2023. Due to the complex interaction between liquid, gas, and plasma, the pre-breakdown process in water under quasi-static moderate electric fields, namely the development of subsonic streamers, was unclear…
