Unit Operations: uses and methods
solves two-phase flash evaporation for a given K value, or calculates the heat exchanger outlet state.
Applicable scope and calculation boundary
flash evaporation uses the input constant K and does not automatically call the physical property library; the heat exchanger is a counterflow ε–NTU model with constant heat capacity.
model and reference method
Rachford–Rice；counterflow ε–NTU。
model version: 1.0.0. The results are used for scientific research, exploration and teaching, please interpret according to the model conditions.
