Deskripsi

Fluid flows with four vortices were simultaneously formed on water surface based on photothermal effect induced by a laser beam of 1.55 μm wavelength. With the illumination of an optical power of 60 mW, the peak velocity of each vortex flow was reached to 1200 μm/s. Influence of optical power and attack angle on the vortex flows has been investigated. The mechanism of photothermal formation was analyzed with the assistance of a finite-element simulation.
