摘要
Abstract
The influences of factors such as expansion rate, exciting frequency, heat transfer condition, etc. on
refrigeration efficiency of the pressure wave refrigerator are investigated numerically. The results indicate that
the refrigeration efficiency increases with the increase of expansion rate and there exists an optimal exciting
frequency( fopt ) for a constant operating condition. The refrigeration efficiency is increased significantly by
means of improving the heat transfer condition outside the tube' s wall and the discharged gas will come back
into the tube when the exciting frequency drifts off fopt.关键词
