Conductionand convectionare similar in that both mechanisms require material medium, but the difference is that convection requires the presence of fluid motion.And heat transfer through a liquid or gas can be by convection or conduction, depending on if there is presence ofbulk fluid motion. In ...
piping system for transfer of heat from a gas to a liquid or gas through the pipes stating.ROBERT WADHAM
These transitions are easy to handle and cost-effective, the lack of liquid material eliminates the risk of leakage, and hence there is no need for encapsulation. The main drawback of these systems is the small heat of fusion. Solid or liquid to gas transitions have high latent heat of ...

Convection is a combined type of heat transfer, occurring in a fluid (liquid or gas), which includes heat conduction and fluid motion. 2.1 Heat Conduction This kind of heat transfer is present within a substance and is associated with the energy of the molecules, atoms, and their components....

A simple but common heat exchanger application in a chemical process plant is cooling a hot liquid or gas product from the process (called the “process fluid”) to a temperature low enough that it can be safely stored. The coolant is likely to be air or water, which would be heated in...
