Heat transfer can be achieved by conduction, c onvection or radiation. Conduction is the form of heat that exists due to direct contact without movement. Convection is the transfer of h eat due t o the bulk m ovem ent of fluid s. This heat transfer is achieved by the movement of molecules wi thin the fluid.

This paper uses example of each type of heat transfer; conduction, convection, and radiation. When breaking down conduction we understand it is the physical transfer of heat. Two objects are touching and the heat from one object transfers to the other object to warm it.

In this paper, we analyse the combined effect of thermal radiation and radiation absorption on mixed convective heat and mass transfer flow of a viscous, electrically conducting fluid through a porous medium past a semi-infinite porous plate. Using perturbation technique the equations governing the flow, heat and mass transfer are solved.

Radiation and Chemical Reaction Effects on MHD Free Convection Flow of a Uniformly Vertical Porous Plate with Heat Source G. Vidyasagar. 1. B. Ramana. 2. P. Mohan Krishna. 3. Abstract: In this paper deals with the combined effect of thermal radiation and heat source on the MHD free convection heat and mass transfer flow of a.

Radiation or radiant heat transfer, involves the transfer of heat by electromagnetic radiation that arises due to the temperature of a body. CONDUCTION Conductive Heat transfer takes place as conduction if there is a temperature gradient in a solid or fluid Conduction will take place if there exist a temperature gradient in a solid (or stationary fluid) medium.

The major types of insulation are associated with the major types of heat transfer: Reflectors for example are used to reduce radiative heat transfer by reflecting electromagnetic radiation. Fibrous materials or spaces are used to reduce conductive heat transfer by reducing physical contact between objects and using materials with low thermal conductivity and therefore a good thermal resistance.

Conduction, Convection, and Radiation Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers, Conduction, Convection, and Radiation.The first kind of heat transfer, conduction, is heat transferring through direct contact of materials.This would be the same thing as a pan on the stove.

The heat flux boundary condition and radiation heat transfer due to solar energy applications using porous medium have great practical interests in modern engineering, such as porous media heat transfer in a solar tower receiver, distributed radiative and convective climate within a cropped greenhouse, thermal performance of solar air heaters of double-parallel flow and double-pass counter.
