Abstract
Non condensing gas flow and heat transfer during venting of vessels are studied using experiments and analysis. A high pressure helium supply vessel is connected to a low pressure receiver via orifice and tubing. A single control volume analysis and a multi-dimensional analysis are used to predict pressure and mass-averaged temperature in the supply. Experiments utilizing transient PVT methods are conducted to obtain transient pressure and mass-averaged temperature data for validating the analysis. Measured transient pressures and mass-averaged temperatures in the supply are reproduced by analysis. Heat transfer is due to natural convection except for the early part of transfer.
