In previous chapters heat transfer by convection or just convection was treated only to the extent that it provides a linear boundary condition of the 3rd kind for conduction problems when the heat transfer coefficient is assumed constant. In this chapter the physical phenomenon of convection is described in more detail.

There are only two fundamental physical modes of energy transfer, conduction and radiation. In conduction, energy slowly diffuses through a medium from a point of higher temperature to a point of lower temperature, whereas in radiation, energy is transmitted with the speed of light by electromagnetic waves (or photons), and a transmitting medium is not

Heat Transfer by Forced Convection
Proceedings of the Physical Society, 1959Heat transfer between a solid (metal sphere) and a fluid in forced convection at higher Reynolds numbers was studied. The relation between heat transfer, friction-drag force, and drag coefficient was established and the values of drag coefficient are exhibited for different Reynolds numbers.

Being the second mode that traditionally is encountered in the study of heat transfer, with the analysis of convection we learn on the heat transfer process that is executed by a fluid stream. The stream purposefully acts as a heat carrier between two moving media in relative motion coming in contact.

Convective Heat and Mass Transfer
2009This chapter on convective heat and mass transfer starts out from Prandtl’s original chapter Heat Transfer in Flowing Liquids. We will treat free convection flows, caused by the density changes in the fluid due to temperature and concentration gradients. These cause a lift in the gravitational field, which in turn causes convection flows.

2011 International Conference on Materials for Renewable Energy & Environment, 2011
In this paper, numerical investigation using SIMPLE algorithm with QUICK scheme for enclosure natural convection and heat transfer with building envelop has been conducted. The results suggest that the flow and heat transfer are influenced by the thickness and the thermal conductivity of building envelop.

Effects of Convection in Heat Transfer
1994When there is a velocity field present in the problem domain, heat is transported by the medium of convection as well as diffusion. The differential equation governing convective-diffusive heat transfer is reproduced here from Chapter 2.

Convective Heat and Mass Transfer
2011This book was developed during Professor Ghiaasiaan's twelve years of teaching a graduate-level course on convection heat and mass transfer. It is ideal for a graduate course covering the theory and practice of convection heat and mass transfer. The book treats well-established theory and practice but is also enriched by its coverage of modern areas ...

Forced Convection Heat Transfer
2015Convection is the term used for heat transfer mechanism, which takes place in a fluid because of a combination of conduction due to the molecular interactions and energy transport due to the macroscopic (bulk) motion of the fluid itself. In the above definition, the motion of the fluid is essential otherwise, the heat transfer mechanism becomes a ...
