WebThe 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 ... WebFt is correction factor, on LMTD for co-current and cross-flow heat exchangers. Ft is one for pure countercurrent flow. Minimum value of Ft should be between 0.9 and 0.95. Ft is a measure of heat transfer efficiency and temperature cross. A low value of Ft indicates reverse heat flow in some part of the exchanger.

WebA plate-fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between ... This allows for the two fluids to result in crossflow, counterflow, cross-counterflow or parallel flow. If the fins are designed well, the plate-fin heat exchanger can work in perfect countercurrent arrangement.
