Step 3

If two-phase flow is likely then we will use DIERS methodology to determine the two-phase venting requirement based on using the two-phase homogeneous sizing method describe by J.C. Leung from the article, "Simplified Vent Sizing Equations for Emergency Relief Requirements in Reactors and Storage Vessels".   Download

Step 3-A

Transfer the process data from the single-phase fire and from the vessel volume calculator by clicking the transfer buttons.  Also input the additional physical property data at "Set" and "Relieving"  conditions to run the homogeneous two-phase relief model.
