Continuing its policy of demystifying technology, Alfa Laval has produced an updated version of its pamphlet ” The theory behind Heat Transfer” which provides a simple yet detailed explanation of how and why heat is transferred from one medium to another.

Within its 12 pages the pamphlet explains the natural laws of physics which dictate that  the driving energy in a system must flow until equilibrium is reached. Therefore, heat, as long as there is a temperature difference, heat leaves the warmer body or the hotter fluid and transfers to the colder medium. It then goes on to discuss direct and indirect heat exchangers before concentrating on the indirect variety, starting with how different physical characteristics dictate thermal performance and demonstrating how to calculate heat load and heat transfer coefficient.
