Detailed Description

Model for heat transfer unit operation rating It is a FlashDrum with 0/one/many RatingHeat-derived subobjects that perform the actual ratings. Use to represent the utility side of the heat transfer. The process-side is pointed to by the processSide option.

Options:

  • nRatings Number of RatingHeat subobjects, valid range 0..INT_MAX, defaults to 0

#include <libpf/units/HeatTransfer.h>
