Abstract :
The paper presents a liquid jet in thin films (height varies from micro to nanometers) and the study of its dynamics under the effects of the thin film´s dimension and viscosity. Furthermore, the penetrating jet velocity is investigated in terms of the laser energy and the distance between the laser focus and the targeted gas bubble surface. In the microchannel, strong shear stress ruptures part of the gas bubble and Rayleigh-Plateau instability further shattered it into small bubbles. On the other hand, in the nanochannel, the nanojets accelerate liquids with thickness of hundreds of nanometers.
