Geankoplis 4th ed. 4.5‐4. Water flowing at a rate of 13.85 kg/s is to be heated from 54.5 to 87.8oC in a double‐pipe heat exchanger by 54,430 kg/h of hot gas flowing counterflow and entering at 427oC ( 1.005 / ).
Heat exchangers are devices that regulate efficient heat transfer from one fluid to another. There are two main types of heat exchangers. The first type of a heat exchanger is called the recuperative type, in which heat are exchanged on either side of a dividing wall by fluids; .
Heat exchangers are units designed to transfer heat from a hot flowing fluid to a cold flowing fluid. Classification of Heat Exchanger. Heat Exchanger Types. According to flow arrangement. According to type of construction. There are many types of heat exchangers in use: Concentric tube (double pipe) Counter-flow or parallel flow.
A heat exchanger is a component that allows the transfer of heat from one fluid (liquid or gas) to another fluid. Reasons for heat transfer include the following:
Algebraic expressions for the correction factor Fhave been developed for vari- ous shell-and-tube and cross-flow heat exchanger configurations [1–3], and the results may be represented graphically. Selected results are shown in Figures 11S.1 through 11S.4 for common heat exchanger configurations.
3.1 Function and configuration of heat exchangers Heat exchanger goal : get energy from one fluid mass to another. Simple or composite wall of some kind divides the two flows and provides an element of thermal resistance between them. Figure 3.1 Heat exchange.
To introduce and apply basic heat exchanger design concepts to the solution of industrial heat exchanger problems. Primary emphasis is placed on fundamental concepts and applications. Also, more emphasis is placed on analysis and less on empiricism.
