A set of efficient wind heating system that can match unstable wind energy as energy input is proposed. Based on computational fluid dynamics simulation (CFD), the key parameters of the system were analyzed, such as the fluid height and the input rotational speed, on the heating performance of the system. The experimental system was established based on the simulation system structural parameters and simulation conditions. The results of simulation analysis and experimental results show that CFD is feasible and effective for the analysis of wind thermal efficiency, and the effect of layered hydrodynamic stirring is obvious. Within the experimental range, the higher the fluid height, the greater the stirring speed, the better the thermal effect .
