Two Bifurcation Transition Processes in Floating Half Zone Convection of Larger Prandtl Number Fluid
Processes of the onset oscillation in the thermocapillaxy convection under the Earth's gravity are investigated by the numerical simulation and experiments in a floating half zone of large Prandtl number with different volume ratio.

Stationary statistical properties of Rayleigh-Bénard convection at large Prandtl number
This is the third in a sequel in our study of Rayleigh-Bénard convection at large Prandtl number. More specifically we investigate if stationary statistical properties of the Boussinesq system for Rayleigh-Bénard convection at large Prandtl number are ...

Prandtl-Blasius temperature and velocity boundary-layer profiles in turbulent Rayleigh-Bénard convection [PDF]
The shapes of the velocity and temperature profiles near the horizontal conducting plates' centre regions in turbulent Rayleigh–Bénard convection are studied numerically and experimentally over the Rayleigh number range 108 ≲ Ra ≲ 3 × 1011 and the ...

On the Cell Broadening of Mesoscale Cellular Convection in a Well‐Mixed Boundary Layer
Abstract Understanding what controls the horizontal scale of mesoscale cellular convection is central to explaining cloud self‐organization and its radiative impacts. Using a hierarchy of large‐eddy simulations, we investigate cell broadening in a well‐mixed boundary layer by isolating the roles of radiation, cloud microphysics, and water vapor.

Large Eddy Simulations of the Atmospheric Boundary Layer Over Satellite‐Sensed Sea Ice Maps
Abstract Surface heterogeneity in the marginal ice zone (MIZ) causes multiscale secondary atmospheric circulations that are challenging to model or observe. The absence or inadequate representation of these circulations in ocean‐atmosphere exchange schemes in climate models is partially responsible for the underestimation of Arctic sea ice loss ...

Diffusion Processes in the A-Model of Vector Admixture: Turbulent Prandtl Number
Using analytical approach of the field theoretic renormalization-group technique in two-loop approximation we model a fully developed turbulent system with vector characteristics driven by stochastic Navier-Stokes equation. The behaviour of the turbulent

Abstract The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (GWs) generation and upward coupling during a southwest vortex (SWV) event over the Tibetan

Weakly stratified laminar flow past normal flat plates [PDF]
Numerical computations of the steady, two-dimensional, incompressible, uniform velocity but stably stratified flow past a normal flat plate (of unit half-width) in a channel are presented.

Weak Turbulence in Small Prandtl Number Convection in Porous Media
The dynamics of weak turbulence in small Prandtl number convection in porous media is substantially distinct than the corresponding dynamics for moderate and large Prandtl numbers.

Turbulent Prandtl Number and its Use in Prediction of Heat Transfer Coefficient for Liquids
A theoretical study is performed to determine the turbulent Prandtl number (Prt ) for liquids of wide range of molecular Prandtl number (Pr=1 to 600) under turbulent flow conditions of Reynolds number range 10000- 100000 by analysis of experimental ...
