The more chains of spring-connected particles we can use, the faster the energy can be transferred. The number of chains is proportional to the cross-sectional area of the cylinder, so the rate of heat transfer is also proportional to the cross-sectional area: dQ dt ∝ A (5.4.1) (5.4.1) d Q d t ∝ A.Heat transfer enhancement is categorized into passive and active methods. Active methods need external power to input the process; in contrast, passive methods do not require any additional energy to improve the thermohydraulic performance of the system. Passive methods are widely used in both experimental and numerical … So, there are three main methods of transferring heat: radiation, convection/mass transfer, and conduction. Presumably radiation is not a major method of heat transport between the core and the crust, because it requires transparent materials (or a vacuum), and I don't think there is much of either in the mantle. Microwave ovens use a type of heat transfer called radiation. Unlike conduction or convection, which rely on direct contact or the movement of air or liquid, radiation heats the food through waves of energy. The microwaves penetrate the food and cause the molecules to generate heat, without the need for a medium to transfer the heat.
