混凝土表面对流换流系数测试研究

Probe into Test Method of Heat Convection Coefficient of Concrete

根据传热学原理,确定了对流换热系数测试方案,测量了混凝土表面自然对流换热系数和受迫对流换热系数.结果表明,混凝土表面对流换热系数与风速基本呈线性关系.根据该关系所提出的建议计算式,希望能为今后的工程应用和科研提供参考.

Based on heat transmission theory, the test scheme of surface convection coefficient of concrete in natural and forced condition was determined, and the relationship between surface convection coefficient of concrete and wind velocity was discussed. The test results indicate that there is linear relationship between surface convection coefficient of concrete and wind velocity. An equation hoping that it can serve for engineering practice and research is proposed.
