Physics of Fluids, Volume 35, Issue 3, March 2023. We study the effect of filter anisotropy and sub-filter scale (SFS) dynamics on the accuracy of large eddy simulation (LES) of turbulence, by using several types of SFS models including the dynamic Sma…
Physics of Fluids, Volume 35, Issue 3, March 2023. Thermally driven flows of superfluid 4He display unique features, often related to the presence of quantized vortices—line singularities embedded in the liquid. Here, we focus on turbulent round jets, …
Physics of Fluids, Volume 35, Issue 3, March 2023. Numerical modeling of ship bow waves is still hard work, partly due to their multiscale features. Direct three-dimensional (3D) computational fluid dynamics simulation could be an appropriate choice to…
Physics of Fluids, Volume 35, Issue 3, March 2023. In the present study, the dry reforming of methane (DRM) has been simulated in fluidized-bed reactors using the multiphase particle-in-cell model. The model was meticulously built to investigate the ef…
Physics of Fluids, Volume 35, Issue 3, March 2023. Inferring cryogenic cavitation features from the boundary conditions (BCs) remains a challenge due to the nonlinear thermal effects. This paper aims to build a fast model for cryogenic cavitation predi…
Physics of Fluids, Volume 35, Issue 3, March 2023. In this paper, the method of generating inflow turbulence based on turbulence fluctuation library (TFL) in direct numerical simulation (DNS) of the hypersonic turbulent boundary layer (TBL) is investig…
Physics of Fluids, Volume 35, Issue 3, March 2023. The Lagrangian transport in the laminar incompressible flow in a two-dimensional square cavity driven by a harmonic tangential oscillation of the lid is investigated numerically for a wide range of Rey…
Physics of Fluids, Volume 35, Issue 3, March 2023. Demand is growing for a larger catalogue of experimental techniques to measure flow rates through micro-/nanoscale systems for both fundamental research and device development. Flow emerging from a hol…
Physics of Fluids, Volume 35, Issue 3, March 2023. Iterative steady-state solvers are widely used in computational fluid dynamics. Unfortunately, it is difficult to obtain steady-state solutions for unstable problems caused by physical instability and …
Physics of Fluids, Volume 35, Issue 3, March 2023. The Savonius wind turbine is a vertical-axis wind turbine invented in 1930s consisting of a cylindrical drum with semi-circular blades attached to the drum. It is popular for its simple design, low cos…
