SIMULATION OF HYDROMECHANICS AND HEAT TRANSFER OF ELECTROCONTROLLED FLUIDS IN NARROW CHANNELS-CAPACITORS OF SPECIAL HEAT EXCHANGER DEVICES

摘要

The results of investigation of rheophysical properties of thermally stable dielectric controllable heat carrier - electrorheological fluid on the basis of hydrated aluminum oxide are presented. Considering obtained experimental data, a numerical solution of conjugated problem of hydrodynamics and heat transfer in a flat channel of electrorheological fluid (ERF) with the flow curve, described by a modified Bulcley-Gershel rheological model is received and discussed. It is shown, that electrorheological effect leads to the increase of an average over the channel length Nusselt number up to 17%.
