Conduction Heat conduction is the transfer of heat from one part of a body to another part of the same body, or from one body to another body in physical contact with it, without appreciable displacement of the particles of the body. Energy transfer by conduction is accomplished in two ways. The first mechanism is […]

The process of heat exchange between two fluids that are at different temperatures and separated by a solid wall occurs in many engineering applications. The device used to implement this exchange is called a heat exchanger, and specific applications may be found in space heating and air-conditioning, power production, waste heat recovery and...

There are some criteria for a successful heat exchanger design.  These principles are given below The process requirements which are accomplishing the thermal change on the streams within the allowable pressure drops, and retaining the capability to do this in the presence of fouling until the next scheduled maintenance period must be...

The thermal design of heat exchangers is directed to calculate an adequate surface area to handle the thermal duty for the given specifications whereas the hydraulic analysis determines the pressure drop of the fluids flowing in the system, and consequently the pumping power or fan work input necessary to maintain the flow.  The most common...
