Popis: In this paper, an experiment system of wind-energy stirring heater has been designed and built. Its heating performance under the rotation speed of 300 r/min has been studied through changing stirring rotor’s layer number or using different working fluids. With the help of CFD numerical simulation method, we studied the influence factors including temperature rise, total heat, heating power of each experimental group, and analyzed why these factors have such an effect. The results show: increasing the layer number of the stirring rotors can increase the motion intensity of working fluid and improve the heating effect; the quantity of effective working fluid in the rotor area can be increased significantly with the increasing of liquid level; the working liquid with high density, low viscosity, low specific heat capacity will be the ideal one.
