Abstract Details

2013, Master of Sciences, Case Western Reserve University, EMC - Mechanical Engineering.
A transient Charge-Hold-Vent (CHV) analytical model has been developed and validated with hydrogen experimental CHV data. The model was found to be within 7% agreement of the data. The model simulates natural convection and jet impingement heat transfer interactions using quasi-unsteady steps in time and tracks the fluids thermodynamic behavior through REFPROP. The additional cooling potential made available through the cyclic venting technique is calculated in the code. The model can simulate multiple CHV cycles and provide predictions on the amount of fluid mass used for each cycle. The impact of varying tank geometry, nozzle position, and fluid type may be simulated and considered when planning future CHV tests.
