Describe in detail about the different modes of heat transfer with examples.
Answers
Explanation:
Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass.
Answer:
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own. For example, the thermal environment of a building is influenced by heat fluxes through the ground (conduction), and the building envelope (mostly convection and radiation).
Conduction is heat flux through solid materials. gSKIN® Heat Flux Sensors can measure conductive heat flux (see picture on the left). Examples of conductive heat flux are:
