Natural convection flow on a sphere through porous medium in presence of heat source/sink near a stagnation point

Mathematical Modelling and Analysis, 2008
Steady natural convection boundary‐layer flow in the neighbourhood of lower stagnation point of a heated sphere embedded in a saturated porous medium in presence of heat source/sink is considered.

Journey to the center of stars: The realm of low Prandtl number fluid dynamics [PDF]

Physical Review Fluids, 2021
The dynamics of fluids deep in stellar interiors is a subject that bears many similarities with geophysical fluid dynamics, with one crucial difference: the Prandtl number. The ratio of the kinematic viscosity to the thermal diffusivity is usually of order unity or more on Earth, but is always much smaller than one in stars.

The Hydrothermal Wave Of Large-Prandtl-Number Fluid In A Shallow Cavity

, 2007
The hydrothermal wave was investigated numerically for large-Prandtl-number fluid (Pr = 105.6) in a shallow cavity with different heated sidewalls. The traveling wave appears and propagates in the direction opposite to the surface flow (upstream) in the ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

Fire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

Steady Prandtl Layer for Compressible Fluids

Despite its importance, there have been few PDE results to investigate Prandtl layers for compressible fluids, in which the thermal boundary layer for the temperature field interacts with the classical velocity Prandtl boundary layer in a strong nonlinear fashion. We establish local-in-$x$ well-posedness of Prandtl layers for steady compressible fluids

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

Influence of Aspect Ratio on the Onset of Thermocapillary Oscillatory Convection in a Floating Half Zone of Large Prandtl Number Fluid

, 2003
The onset of oscillatory thermocapillary convection in a floating half zone of 10 cst silicon oil (Prandtl number 105.6) is studied by the three-dimensional and unsteady numerical simulation in microgravity environment (g=10~{-4}_{gearth}).
