Basics of Heat Transfer

In the simplest of terms, the discipline of heat transfer is concerned with only two things: temperature, and the flow of heat. Temperature represents the amount of thermal energy available, whereas heat flow represents the movement of thermal energy from place to place.

Heat Transfer Fundamentals
The transfer of heat is an integral part of many industrial processes. Moreover, heat transfer affects our everyday lives - from an oven heating our dinner to the wind cooling us on a hot summer day. Thus, it is important that the engineer understands how to apply the basic principles of heat transfer to solve real-world problems. This course covers the fundamentals of heat transfer, including conduction, convection and radiation. - 3 PDH

Heat Exchanger Fundamentals
Because of the importance of heat exchangers in the design of so many processes and systems, it is important that the engineer possess at least a basic knowledge of the types of heat exchangers and how they operate. This course covers the fundamentals of heat exchangers, including the different types and how they operate. - 2 PDH

 

Heat Exchangers

IA heat exchanger is a device in which energy is transferred from one fluid to another across a solid surface. Exchanger analysis and design therefore involve both convection and conduction. Radiative transfer between the exchanger and the environment can usually be neglected unless the exchanger is uninsulated and its external surfaces are very hot.

 

 

Heat exchanger

A heat exchanger is a device for transferring heat from one fluid to another, where the fluids are separated by a solid wall so that they never mix. They are widely used in refrigeration, air conditioning, space heating, power production, and chemical processing. One common example of a heat exchanger is the radiator in a car, in which the hot radiator fluid is cooled by the flow of air over the radiator surface.

 

Heat Exchanger in Bio-Chemical Process

The main purpose of the heat exchanger in a bio-process is sterilization. There are other ways to kill unwanted organisms (contaminants), such as using chemicals and filtration. However, using heat energy seems to be the best way to sterilize feed before entering to the reactor.
