摘要 应用红外热像仪对水介质中HP-LVG4和HP-S背面温度场进行了拍摄,结果表明在加热功率密度基本相当时, HP-LVG4内壁温平均值相对于HP-S降低了18.1%;在平均内壁温基本相当时,HP-LVG4的加热功率密度比HP-S提高了29.3%。以上结果说明,红外热像仪可以较好地应用在纵向涡强化传热研究中。 Heat transfer can be enhanced by longitudinal vortex in narrow rectangular channels. Thermal infrared imager has been used to measure the temperature field of heated plate with 4 pairs rectangular block longitudinal vortex generators and smooth heated plate. The experimental results showed that the average value of inside wall temperature can be decreased by 18.1% or the heated power can be increased by 29.3%.
