-
摘要: 建立了激光实时全息监测装置,以连续观察水平圆管外的自然对流传热。探索了实验条件,得到了传热系数与时间的关联式。Abstract: A laser realtime holographlc interferometry system has been buiIt to observethe natural convection heat transfer from a horizontal round tube.The optimal experimentalconditions have been studied and the correlation for predicting heat transfer coefficientswhich exhibit time-dependence characteristic has been obtained.
