USING THE DISCONTINUOUS GALERKIN METHOD FOR SOLVING A SYSTEM OF EQUATIONS OF THE DYNAMICS OF WATER DROPLETS IN AN AIR FLOW

摘要

The paper presents a system of equations that describe the dynamics of water droplets suspended in an air flow and a method for solving this system. The numerical method is based on a finite-element method, namely, the high-accuracy Galerkin method with discontinuous basis functions. Examples of computations of an air flow containing water droplets around a semi-cylinder and a hemisphere are given. The capture coefficient of suspended droplets incident on critically important surface areas is estimated. The computed results are compared with experimental data. The efficiency of the proposed approach is compared with available solutions.
