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:
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 / ).
Chapter. (4) Heat Exchanger. Goals: By the end of today’s lecture, you should be able to: Learn how to deal with heat exchanger problems. Learn how to design and select heat exchanger according to the application. What Are Heat Exchanger? Heat exchangers are units designed to transfer heat from a hot flowing fluid to a cold flowing fluid.
30 Δεκ 2021 · In this article, you will learn what is a heat exchanger? Its diagram, parts, working, advantages, uses, and types of heat exchangers [PDF].
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.
1er mars 2008 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. Exception : Direct-contact form of heat exchanger. Steam is bubbled into water.
Some examples of common design parameters to be taken into account are: • Flow rate of both fluid streams • Inlet and outlet temperatures of both streams • Operating pressure of both streams • Allowable pressure drop of both streams • Fouling resistance for both streams • Physical properties of both streams • Type and ...
