Analytical solutions, using the boundary layer equations, of some simple convection heat transfer problems, especially the convection with laminar flow, have been presented in this chapter. Solution of momentum equation for laminar flow over a flat plate by Blausius and solution of the integral momentum equation of laminar flow by von Karman are ...

Natural and forced convection heat transfers are treated in this chapter. Emphasis is placed on the heat-transfer phenomena around a sphere, a cylinder, and a flat plate because of their practical importance.

In the present article, the improvement of nanofluid heat transfer inside a porous cavity by means of a non-equilibrium model in the existence of Lorentz forces has been investigated by employing control volume based finite element method.

Numerical analysis of convective heat transfer coefficient for building facades
Journal of Building Physics, 2018The latest architectural trends demand an extensive use of glazed curtain walls running from building floor to ceiling. While glazing poorly controls the heat flow, it is important for viewing, daylighting, and solar design features. In order to evaluate

Heat transfer in convective turbulence [PDF]
Nonlinearity, 1996 We investigate the bulk scaling of the convective heat transport in the Boussinesq equations. An a priori bound on the scaling exponent is obtained without making any assumptions on the turbulent fluctuations. If horizontal gradients of temperature fluctuations are relatively small near the boundary then different scaling regimes are obtained.

Convective Heat Transfer and Infrared Thermography
Annals of the New York Academy of Sciences, 2002Abstract: Infrared (IR) thermography, because of its two‐dimensional and non‐intrusive nature, can be exploited in industrial applications as well as in research. This paper deals with measurement of convective heat transfer coefficients (h) in three complex fluid flow configurations that concern the main aspects of both internal and external cooling ...

The major portion of this chapter will be devoted to a discussion of the “mixing length theory,” or “MLT,” of convective heat transport in stars. Although this theory has many faults, it has served as a useful phenomenological model for a description of stellar convection for more than thirty years. Almost all numerical simulations of stellar evolution

Basics of heat transfer: Convection
2023This chapter discusses the mechanism of heat transfer through the motion of the bulk fluid also known as convection. This heat transfer can be either forced or free depending on how the initiation of the fluid motion takes place. In forced convection, a pump or a fan is used to force the fluid to flow through a pipe or over a surface.

Convective heat transfer at a stretching sheet [PDF]
Acta Mechanica, 1993 Analysis of convection flow and heat transfer of a viscous heat-generating fluid near an infinite vertical stretching surface is carried out. The effects of free convection and the presence of heat generation/absorption on the flow and heat transfer characteristics are considered.

As we consider simultaneous fluid flow and heat transfer in porous media, the role of the macroscopic (Darcean) and microscopic (pore-level) velocity fields on the temperature field needs to be examined. Experiments have shown that the mere inclusion of u D · ∇ 〈T〉 in the energy equation does not satisfactorily account for all the hydrodynamic effects.
