Description
This lecture covers the fundamentals associated with thermal energy, including the terminology and the basics behind the three (3) modes of heat transfer namely conduction, convection, and radiation. The design and operation of heating and cooling vessels and heat exchangers are thoroughly reviewed. The lecture will also describe the factors that affect thermal exchange through conduction and convection. Emphasis is mainly on uni-directional and counter-current heat exchangers commonly found in a brewery environment.
Finally, we will walk you through basic calculations of sensible heat, convection and conduction heat transfer and finally heat exchanger. Each of those are related to practical applications in a brewery.
