提出了在强迫对流换热条件下，根据实测壁面瞬时温度，计算对流换热气体流动特性，并进行了实验验证．在此基础上，介绍了用快速响应温度传感器测试倒拖运行单缸风冷柴油机缸盖火力面局部瞬时温度以及缸内对流换热气流特征速度的研究结果． Proposed in the forced convection heat transfer conditions, according to the measured wall instantaneous temperature, calculate the convection heat transfer gas flow characteristics and experimental verification. On this basis, the results of the research on the instantaneous temperature of the thermal face of the cylinder head of a single-cylinder air-cooled diesel engine with inverted dragging and the characteristic velocity of convection heat transfer in the cylinder with the rapid response temperature sensor are introduced.
