The Equations of Motion for Thermally Driven, Buoyant Flows

Effects of Brownian motion and Thermophoresis on MHD Mixed Convection Stagnation-point Flow of a Nanofluid Toward a Stretching Vertical Sheet in Porous Medium

This article deals with the study of the two-dimensional mixed convection magnetohydrodynamic (MHD) boundary layer of stagnation-point flow over a stretching vertical plate in porous medium filled with a nanofluid. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis in the presence of thermal radiation. The skin-friction coefficient, Nusselt number an...

The Equations of Motion for Thermally Driven , Buoya nt Flows Ronald

In this paper a set of approximate equations is derived which is applicable to very nonadiabatic, nondissipative, buoyant flows of a perfect gas. The flows are assumed to be generated by a heat source in which the heat is added slowly. The study is motivated by the occurrence of such flows in fires.There, the time scale associated with the fire growth and resultant fluid motion is usually long ...

Existence and Measurability of the Solution of the Stochastic Differential Equations Driven by Fractional Brownian Motion

An analytical verification test for numerically simulated convective flow above a thermally heterogeneous surface

An analytical solution of the Boussinesq equations for the motion of a viscous stably stratified fluid driven by a surface thermal forcing with large horizontal gradients (step changes) is obtained. This analytical solution is one of the few available for wall-bounded buoyancy-driven flows. The solution can be used to verify that computer codes for Boussinesq fluid system simulations are free o...

Urban Fluid Dynamics – Thermally Driven Environmental Flows Entrainment Dynamics of Shear-Free Convective Boundary Layers Growing in Linearly and Discretely Stratified Fluids

Boundary layers driven by surface buoyant forcings are commonly observed in the environmental flows. An atmospheric example of such boundary layer is the so-called convective boundary layer (CBL), which is driven by buoyancy production at the heated underlying surface during the daytime conditions. The buoyancy is defined as b= g − ( ρ -ρ0 )/ρ0 , where ρ is the density of the fluid, ρ0 is the r...
