Mar 01, 2014 · The pumping powers of the heat exchanger in hot and cold fluid sides can be defined by : (46) P 1 = m ̇ 1 Δ P 1 ρ 1 (47) P 2 = m ̇ 2 Δ P 2 ρ 2. Thus, the operating cost can be approximated as follows : (48) OP = C OP Y (P 1 + P 2) Therefore, the total cost of heat exchanger becomes: (49) C total = CP + OP = C M M HX + C OP Y (P 1 + P 2) In heat exchanger applications, stainless steel finned tubes are often required for the optimum design for a specific application. The heat exchanger fin to tube joint is a T joint configuration and from the advantageous characteristics of laser welding previously described in Chapter 2 and reference to Fig.Making best use of pressure drop,the paper developed an optimizing design software for shell and tube heat exchanger based on MATLAB 7.6.By varying the structures of heat exchanger,fully using of pressure drop between shell and tube gap can improve heat transfer coefficient and reduce heat exchange area.By analysis of the designed case,the results prove that the heat transfer coefficient ...
