Wave mixing in oscillatory-type power plants

Abstract

We have investigated processes of wave mixing in oscillatory-type power plants and presented the results in the paper. The flow in the power plant has been simulated by solving a set of 2D nonstationary Navier–Stokes equations for viscous uncompressible liquid. The flow field was formed by blade vibration and, as a result, the triangle deformed mesh has been used. The marker method has been used as the basic method for calculating the evolution of the admixture. The information of computations is processed using special criteria of the mixture quality. The influence of frequency and amplitude on the mixing intensity has been investigated. The consumed power has been estimated. The obtained information forms a basis for determining optimal modes of power plant operation in terms of power consumption–mixing efficiency.
