A Method for Predicting the GEM Cushion Pressure

概要

論文の詳細を見る
An approximate theory for predicting the GEM's cushion pressure has been derived by considering the effect of viscosity, i. e. the mixing of jet with the surrounding fluid at rest, and compared with experiments. The theory not only predicts the phenomena qualitatively, but, by suitably choosing some empirical constants, e. g. the jet-spread parameter, gives fairy good agreement with experiments.In order to check the substantial validity of the theory, however, further minute measurements of jet motion should be continued.
