Direct numerical simulation and large-eddy simulation of stationary buoyancy-driven turbulence [PDF]
, 2010 We report direct numerical simulation (DNS) and large-eddy simulation (LES) of statistically stationary buoyancy-driven turbulent mixing of an active scalar. We use an adaptation of the fringe-region technique, which continually supplies the flow with

On Gakerkin approximations for the surface-active quasigeostrophic equations
, 2015 We study the representation of solutions of the three-dimensional quasigeostrophic (QG) equations using Galerkin series with standard vertical modes, with particular attention to the incorporation of active surface buoyancy dynamics.

Energy Science &Engineering, EarlyView.This figure illustrates the optimal near‐wall treatment schemes (first‐layer height and wall function type) for solid–liquid two‐phase CFD of suspended sediment, which are correlated with particle size and flow velocity. ABSTRACT Near‐wall treatment (boundary‐layer meshing and wall functions) is a major uncertainty in solid–liquid two‐phase CFD of ...

On the rise and fall of a ball with linear or quadratic drag [PDF]
, 1999 We review the problem of a vertically thrown ball, with a drag force which is either linear or quadratic in the speed. It is stressed from the outset that these two types of drag correspond to specific ranges of the Reynolds number ...

Heat Transfer, EarlyView.ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, EarlyView.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that
