Analytical calculation of hydraulic characteristics of jet-cavitation fluid mass flow stabilizers

The paper provides analysis of devices using cavitation mass flow stabilization effect in the working process. The object of present study is the jet-cavitation fluid mass flow stabilizer of the "pipe-pipe" type. To create the method of its calculation a new hypothesis about the causes of the cavitation mass flow stabilization effect based on the preservation of the boundary layer at the cavitation has been proposed. Verified method of calculating hydraulic characteristics of the jet-cavitation fluid mass flow stabilizer is proposed. The discrepancy with the experimental procedure is not more than 4% for the mass flow of stabilization. With the help of the method the influence of structural and hydraulic parameters on the mass flow and the width of the stabilization zone were studied. The efficiency of the proposed method was compared with numerical simulations and analytical methods of calculation. (C) 2017 The Authors. Published by Elsevier Ltd.
