Effect of liquid bridge volume on the instability in small-Prandtl-number half zones

, 1999
A perturbation method is used to examine the linear instability of thermocapillary convection in a liquid bridge of floating half-zone filled with a small Prandtl number fluid.

An analytical, phenomenological and numerical study of geophysical and magnetohydrodynamic turbulence in two dimensions [PDF]

, 2013
In this thesis I study a variety of two-dimensional turbulent systems using a mixed analytical, phenomenological and numerical approach. The systems under consideration are governed by the two-dimensional Navier-Stokes (2DNS), surface quasigeostrophic

A Study on the Applicability of the Linear Superposition Principle to Overland Flow Resistance Based on HR‐PIV Technology

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Previous studies have suggested that the linear superposition principle fails for thin‐layer overland flows, yet direct experimental evidence remains scarce. This work adopts high‐resolution particle image velocimetry (HR‐PIV) to measure the 2D flow fields of grain resistance and form resistance in thin‐layer overland flows.

Evaporation Dynamics From Flowing Water Surfaces

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract In contrast to the wealth of information on evaporation dynamics from placid water surfaces such as lakes and reservoirs, estimating water evaporation from turbulent surfaces of streams remains a challenge. Evidence suggests considerable differences in evaporation rates from flowing water bodies relative to placid surfaces.

Study on the turbulent Prandtl number model for liquid metal flow and heat transfer in a narrow rectangular channel

Frontiers in Energy Research
In order to improve the core power density of liquid metal reactors, plate-type fuel assemblies are typically used, which have obvious advantages in heat transfer capacity.

Assessment of the ellipsoidal-statistical Bhatnagar-Gross-Krook model for force-driven Poiseuille flows [PDF]

, 2013
We investigate the accuracy of the ellipsoidal-statistical Bhatnagar–Gross–Krook (ES-BGK) kinetic model for planar force-driven Poiseuille flows. Our numerical simulations are conducted using the deterministic discrete velocity method, for Knudsen ...
