Abstract

Thermal analysis is carried out for split-flow heat exchangers with an even number of tube passes, arbitrary entrance and exit locations of the shellside flow, arbitrary division of the shellside fluid and variable NTU. A closed form solution is presented for calculating the temperature at a given position and the thermal effectiveness. The thermal performance of the split-flow exchanger is compared with that of the conventional shell and tube exchanger. The shellside pressure drop and the optimum entrance and exit locations of the shellside flow in the split-flow exchanger are discussed.
