Heat can travel from one place to another in several ways. The different modes of heat transfer include: Conduction. Convection. Radiation. Meanwhile, if the temperature difference exists between the two systems, heat will find a way to transfer from the higher to the lower system.

READ MOREConvective Heat Transfer. 17. Convective Heat Transfer. The second type of heat transfer to be examined is convection, where a key problem is determining the boundary conditions at a surface exposed to a flowing fluid. An example is the wall temperature in a turbine blade because turbine temperatures are critical for creep (and thus blade) life.

READ MOREAlthough air can transfer heat rapidly by convection, it is a poor conductor and thus a good insulator. The amount of available space for airflow determines whether air acts as an insulator or conductor. The space between the inside and outside walls of a house, for example, is about 9 cm (3.5 in)—large enough for convection to work

READ MOREConvection. Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water. In forced convection, air or water is forcibly moved across the body surface (such

READ MOREthe basics. Convection is the transfer of internal energy into or out of an object by the physical movement of a surrounding fluid that transfers the internal energy along with its mass. Although the heat is initially transferred between the object and the fluid by conduction, the bulk transfer of energy comes from the motion of the fluid.
