| Abstract: | A three dimensional numerical model based on PHOENICS 3.3 code using porousmedia method was established to simulate fluid flow in the shell tube heat exchanger. Tubes in the heat exchange were described by means of distributed resistance along with volumetric porosity and surface permeability. The model was validated by comparison of computed pressure drops with the experiments by Halle . And a modified code was used to calculate the fluid flow in the main heat exchanger of the 200 MW nuclear heating reactor(NHR 200). |
