is checked before the program runs. If the heat exchanger outside flow is out of the laminar region, a warning sign will be given by the program to reset the heat exchange geometry in order to keep the heat exchanger outside flow in the laminar region. Then several variables are set in this calculation, namely: tinfinite, which equals the fluid inlet temperature; the number of loops at each heat exchanger plate (n loop preset), which equals 2 as an initial value; Scalars b and n loop that both equal 1 as initial values, etc. In the inner calculation loop, the fluid temperature after passing one loop of heat exchanger tubes is first calculated and then the number of tube rounds on each heat exchanger plate (n round) is compared with the pre‐set value (n loop preset) in the if‐clause. If n loop is smaller than n loop preset, the scalars are then calculated as n loop= n loop+1, b=b+1, and the value of t infinite is set as the fluid outlet temperature after passing n loops of heat exchanger tubes. Then the calculation loop goes back to Equation 9‐13 to calculate a new fluid outlet temperature after passing one more loop of heat exchanger tubes. The calculation loop is kept running until the scalar n loop is bigger than n loop preset. Then the temperature of the working fluid at this time will be compared with the preset preferred fluid outlet temperature, which was set as an input, in the outer calculation loop. If this temperature is bigger than the preferred fluid outlet temperature, all the variables will be set back to the original values; the scalars are reset as n loop preset = n loop preset +1, b=1 and the inner calculation loop will run again to calculate the new fluid outlet temperature. Following the same procedure, the fluid outlet temperature is iterated until it reaches the preferred fluid outlet temperature that was set as an input. Then the calculation will stop and the program will export the outputs as: minimum number of plates required to keep laminar flow at the outside of the heat exchanger, the heat source outlet temperature, the number of tube loops in each heat exchanger plate, approximate heat exchanger size, etc. The program flow chart is shown in Figure 9‐10. 113PDF Image | Thermodynamic Cycles using Carbon Dioxide
