摘要：

An experimental study of the splattering and bouncing of water, acetone, and alcohol droplets from a heated plate reveals that the heat transfer per drop exhibits a maximum at a temperature excess of approximately 300°F and that a satisfactory correlation for this maximum Qmax ̄grLd3λ = 8·44(10-4)(ρ2LV2d ̄grVFσggc)0·341 The effect of impact angle is also investigated and the general result is that the normal component of velocity is the important factor. A normalized heat flux-temperature excess curve is presented for the three fluids tested. The maximum point in heat transfer is postulated to result from opposing effects of increasing thermal gradient and decreasing droplet contact time in the splattering process. © 1969.
