以自然风为动力的直接搅拌致热试验

Experimental Study of Heating by Direct Stirring with Natural Wind as the Driving Force

设计了风热转化系统.在自然风中试验并记录风速和水升温的数据,取风速3次方平均值作为理论计算风速,然后进行数据分析.结果表明:在低风速下试验40min,水升温1.21℃,风能转化效率为13.9%.经过分析可得出风力直接致热是完全可行和科学的.

The system is designed to transform wind energy to thermal energy in the experi- ment. The data of wind speed and heated water temperature are recorded by the experiment in natu- ral wind. By taking cubic average of wind speed values the data are analyzed. The results indicate that the temperature of water increases about 1.21 degrees and the ratio of transformed wind ener- gy is 13.9% in 40 minutes at low wind speeds. The analysis shows that getting thermal energy di- rectly from wind is feasible and scientific.
