Analysis and simulation of the drying-air heating system of a Brazilian powdered milk plant
2004
Brazilian Journal of Chemical Engineering
Aiming at simulating air-heating systems, two algorithms were developed for the calculation of finned elliptical-tube heat exchangers, whose basic difference lies in the kind of hot fluid employed: saturated steam or hot liquid. In both cases, a crossflow unit, in which the cold fluid is mixed and always flows on the shell side, is considered. The hot fluid may exhibit multiple passes in the tubes and is assumed unmixed, except for the region between the passes. A comparison between calculated
