Capillary Flow in the Vane-Type Surface Tension Tank: Drop Tower Test Results

Article Preview

Abstract:

The paper studied capillary flow in asymmetry interior corner in the vane-type surface tension tank, and calculated it by analytical solution. Proposed a variable of equivalent corner angle to calculate the parameters of meniscus, and then analyze the capillary flow at asymmetry interior corner. A vane-type surface tension tank model is tested at drop tower to observe the capillary flow at asymmetry interior corner in microgravity condition. The test results are compared with analytical solution results to verify the theory of interior corner flow.
