Physics of Fluids, Volume 35, Issue 3, March 2023. Liquid evaporation from micro/nanoscale pores is widely encountered in cutting-edge technologies and applications. Due to its two- or three-dimensional features, the nano-porous evaporation is less und…
Physics of Fluids, Volume 35, Issue 3, March 2023. The least squares and Green–Gauss gradient schemes have been traditionally studied as two distinct techniques for gradient computation on unstructured meshes in the literature. In this Letter, we show …
Physics of Fluids, Volume 35, Issue 3, March 2023. We study the velocity autocorrelations in an experimental configuration of confined two-dimensional active rotors (disks). We report persistent small scale oscillations in both rotational and translati…
Physics of Fluids, Volume 35, Issue 3, March 2023. Effective ventilation systems are essential to control the transmission of airborne aerosol particles, such as the SARS-CoV-2 virus in aircraft cabins, which is a significant concern for people commuti…
Physics of Fluids, Volume 35, Issue 3, March 2023. The flow is extremely complex within the main flow channel during the operation of the multiphase pump, resulting in constant changes in the vortex structure, disrupting the orderly flow of the existin…
Physics of Fluids, Volume 35, Issue 3, March 2023. Supersonic ejectors are passive gasdynamic devices that compress a low-pressure fluid by utilizing the kinetic energy of a high-pressure fluid in a variable area duct. The ejector consists of a primary…
Physics of Fluids, Volume 35, Issue 3, March 2023. The initial unstable stage associated with keyhole plasma arc welding affects the stability and quality heavily, especially in the non-vertical welding position, which is difficult to control and restr…
Physics of Fluids, Volume 35, Issue 3, March 2023. The vortex induced vibrations of a cylinder tightly confined in a narrow channel were numerically studied in two dimensions. Attached to a linear spring and subject to hydrodynamic forces and torques, …
Physics of Fluids, Volume 35, Issue 3, March 2023. Centrally staged swirl combustion can effectively reduce NOx emission. However, the complex combustion field is susceptible to producing large-scale coherent structures, such as precessing vortex core …
Physics of Fluids, Volume 35, Issue 3, March 2023. An extension of the explicit algebraic subgrid-scale (SGS) stress model (EASSM) of Marstorp et al. [J. Fluid Mech. 639, 403–432 (2009)] is proposed to account for the non-local equilibrium between the …
