Abstract

It is experimentally established that heating of the surface of water by continuous laser radiation at a 1.94-μm wavelength via optic fiber leads to the generation of two jets: a (i) submerged jet directed into the liquid and (ii) a counterjet directed upward into the atmosphere. The jets are generated upon coalescence of the gas cavity formed during the explosive boiling of water caused by the absorption of laser radiation immediately under the edge of the vertical optic fiber. Possible mechanisms of jet formation are discussed.

激光加热液体表面产生的淹没射流

摘要

通过实验确定，通过光纤以1.94-μm波长连续进行激光辐射加热水表面，会导致产生两股射流：（i）浸没在液体中的射流和（ii）射入向上的反射流进入大气。射流是在垂直爆炸光纤边缘附近直接吸收激光辐射引起的水爆炸沸腾期间形成的气腔聚结时产生的。讨论了射流形成的可能机理。
