Fluid Flow mode results for the F4 example simulation

The following table shows the relief valve back pressures for the case in which all valves are relieving (FF 1) at the rated flow conditions. We can see that all the downstream piping has been adequately sized since the back pressure is low for all relief valves.

The following table shows the relief valve back pressures for the case in which total power failure (FF2) occurs at the rated flow conditions. We see that during a total power failure, the relief valves are still appropriately sized, with all back pressure fractions being less than 10%.

The following table shows the relief valve back pressures for the case in which cooling water failure (FF3) occurs. In this case as well, no back pressure fraction exceeds 6% and the relief valves are still appropriately sized.

Additionally, we can observe the heat loss across specified inlet and tail pipes only looking at the temperature difference (DT). The heat transfer across each pipe, including the heat loss method is shown in the following table for the case where all valves are relieving.

After all the fluid has been collected by the common headers, the fluid is sent to the knockout drum where the phases are separated. For each case, the amount of fluid fed to the drum changes, which results in differing vapor and liquid product that is sent to the stack and downstream pump, respectively. The following table shows the mass balance around the drum for each case.
