The effects of refrigerant pressure drop along tube and pressure losses at the tube entrance and exit were accounted for in the heat transfer calculations. The air-side fins were assumed to operate at the fully wet condition and the sensible heat transfer coefficient of the wet fins was assumed...
UAseg,TL is the heat transfer conductance for the thermal liquid in the segment. Tseg,TL is the average liquid temperature in the segment. The fluid properties that the block uses in heat transfer calculations are the average between the value at the inlet and the value in the fluid volume...
Perimeter of tube cross-section for heat transfer—Perimeter of a single tube for heat transfer calculations 0.15 m(default) | positive scalar Pressure loss model—Method of pressure loss calculation due to viscous friction Correlation for flow inside tubes(default) |Euler number per tube row|Pressu...

After the completion of these tasks on site, heat and mass balance calculations were performed for the existing train to confirm the validity of the data. The next step was to determine how to rearrange and modify the existing vessels and what additional vessels would be required to reach...
Calculations have shown that, despite the reduced surface available to the evaporating function generated by use of rows 1 and 2 for the construction of the subcooling heat exchanger 30, the capacity of the remaining portion of the evaporator 24 and the total capacity of the system employing the...
As can be seen from the above calculations, the heat transfer coefficient (hf) of the fin32varies less than 4%, and that any one data set can be used to accurately predict one of the other data sets by simply adjusting the heat transfer coefficient (hT) of the tubes34and36per Hilpert...
