Shell and Tube Heat Exchangers is the Most commonly used heat exchangers. Advantages • Large surface area in a small volume. • Good mechanical layout. • Uses well established fabrication methods. • Can be constructed from a wide variety of materials. • Easily cleaned and maintained. • Well established design procedures

Heat Exchangers – Typical Old Fashion design 1) Define duty: heat transfer rate, flows, temperatures. 2) Collect required physical properties (ρ, μ, k). 3) Decide on the type of exchanger. 4) Select a trial value for U. 5) Calculate the mean temperature difference, ΔTm 6) Calculate area required. 7) Decide on the exchanger layout. 8)...

Heat exchangers are typically classified according to flow arrangement and type of construction. In the first classification, flow can be countercurrent or co current (also called parallel). Heat exchangers can also be classified based on their configuration as tubular, plate and shell & tube heat exchangers. The tubular heat exchanger,...

Radiation Thermal radiation describes the electromagnetic radiation that is emitted at the surface of a body which has been thermally excited. This electromagnetic radiation is emitted in all directions; and when it strikes another body, part may be reflected, part may be transmitted, and part may be absorbed. Thus, heat may pass from one body...
