WitrynaThe working of a shell and tube heat exchanger is fairly simple. One fluid flows inside the tubes and the other through the shell. While flowing they exchange heat which means the cold fluid gains the heat from the hot fluid. So one cold fluid enters the shell (or tube side or channel side) inlet nozzle and comes out of the outlet nozzle as hot ... WitrynaThe E-NTU model defines the heat transfer rate between fluids 1 and 2 in terms of an effectiveness parameter ε: Q 1 = − Q 2 = ϵ Q M a x, 0 < ε < 1, where: Q1 and Q2 are the heat transfer rates into fluid 1 and fluid 2. QMax is the maximum possible heat transfer rate between fluid 1 and fluid 2 at a given set of operating conditions.
