2 dimensional computer modelling on flow in hydraulic turbine generator cooler

Fouling represents an undesirable accumulation of deposits on heat transfer surface. Fouling is a consequence of various mass, momentums, and transfer phenomena involved with heat exchanger operation. The manifestations of these phenomena, though, are more or less similar. Fouling results in a reduc...
