2-PHASE HIGH-SPEED FLOW IN A CREVICE BETWEEN 2 PARALLEL PLATES

In this paper, the results of an experimental study on two phase (air and oil) flow through a crevice between two parallel plates are presen ted. These results are compared to the predictions of an approximate t heoretical model. Four correlations are reported on the dependence of the friction factor on the Reynolds number based on the crevice hydrau lic diameter and the crevice height. Each one of these correlations co rresponds to a specific value of the oil to air volume ratio (mu) in t he range 0 less-than-or-equal-to mu less-than-or-equal-to 0.03. The pe rformance of the theoretical model was deemed acceptable for engineeri ng estimates.
