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.

Convective heat transfer on Mars
AIP Conference Proceedings, 1991An examination was made into the feasibility of using convective heat transfer on Mars to reject the waste heat from a Closed Brayton Cycle. Forced and natural convection were compared to thermal radiation. For the three radiator configurations studied, it was concluded that thermal radiation will yield the minimum mass and forced convection will ...

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.

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.

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.

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 ...
