Related to Boundary layer flow: Turbulent Boundary Layer

boundary layer

n.
The layer of reduced velocity in fluids, such as air and water, that is immediately adjacent to the surface of a solid past which the fluid is flowing.

boundary layer

n
(General Physics) the layer of fluid closest to the surface of a solid past which the fluid flows: it has a lower rate of flow than the bulk of the fluid because of its adhesion to the solid

bound′ary lay`er


n.
the region of a fluid flowing in the immediate vicinity of a body, with the flow reduced by adhesion and viscosity.

The present study involved on a numerical approach on MHD natural convection boundary layer flow from a finite isothermal flat plate of arbitrary inclined surface.
This program focuses on four research aspects: 1) gas exchange processes; 2) carbon cycle, including greenhouse gases (GHG) flux database development for lacustrine ecosystems; 3) energy and greenhouse gas flux measurements, including research and knowledge transfer of key methodological aspects for comprehensive measurement sites; 4) process based biogeochemical modelling for GHGs production and transport in water bodies, as well as state of art large eddy simulation modelling for resolving non-homogeneous and non-stationary atmospheric boundary layer flow over heterogeneous surfaces (e.
The study of slip condition on convective boundary layer flow beside a vertical plate embedded in a porous medium has accepted considerable practical and theoretical awareness.
Tien and Vafai [3] investigated the free convection boundary layer flow in a porous medium, owing to combined heat and mass transfer.
Among his topics are the kinematics of fluid flow, control volume analysis, compressible flow, boundary layer flow, and the computational fluid dynamics of turbulent flow.
In contrast to the Blasius problem, Sakiadis [2] introduced the boundary layer flow induced by a moving plate in a quiescent ambient fluid.
Several authors have studied the characteristic of the boundary layer flow of micropolar fluid under different boundary conditions.
The computational domain was then discretised using trimmed hexahedral cells in the volume, with a prismatic boundary layer mesh near the surface to capture the boundary layer flow.
Sakiadis [1] initiated the study of these applications by considering the boundary layer flow over a continuous solid surface moving with constant speed.
A microscopic interaction between the boundary layer flow field and the local pressure rise upstream of the flame obviously is a key process for the onset of wall flashback and should consequently be represented in any physically sound method for the correlation of flashback limits.
From the abovementioned analysis of the theoretical research results of unsteady boundary layers, essentially important conclusions are made about the fact that the most significant influence on the flow in the boundary layer and, especially, in the boundary layer areas near the walls is caused by low-frequency oscillations that have an impact on the main stream and high-frequency disturbances but do not affect the boundary layer flow.
Reference [5] discussed mixed convection boundary layer flow over a vertical surface for the Darcy model when viscosity varies inversely as a linear variation of temperature.
