Влияние состава наночастиц на свободную конвекцию неньютоновской наножидкости в полости с тепловыделяющим элементом и пористыми ребрами

Abstract

This work is devoted to the study of the nanoparticles material effect on the pseudoplastic nanofluid natural convection in a closed cavity in the presence of a heater and porous fins. The following substances have been used as nanoadditives: Al2O3, Cu, CuO, TiO2. The process is described by non-stationary differential equations based on the conservation laws of mass, momentum and energy based on the non-primitive variables "stream function and vorticity". The pseudoplastic properties of the base fluid have been described by the Ostwald-de Waele power law. The effective nanosuspension parameters have been calculated using experimental correlations reflecting the temperature effect.
