Experiments on the thermo‐hydraulic response of pressure liquefied gases in externally heated tanks with pressure relief

An experimental program is described and experimental results presented for the response of an externally heated horizontal cylindrical tank protected by a PRV and partially filled with a pressure liquefied gas. Measurements of tank pressure, temperatures, mass discharge and void development, along with photography of internal fluid behavior are used to demonstrate the complex thermo-hydraulic behavior as a function of heating and valve position. The results are used to compare some of these parameters with analyses of stratification and void development.
