    Abstract
  • Active control of thermocapillary convective instability is a frontier scientific issue in the field of microgravity hydrodynamics and heat and mass transfer. In order to achieve effective control of thermocapillary convective instability of double-layer fluid, this paper innovatively proposes to use laser photothermal effect to actively control flow, the regulation mechanism of laser photothermal effect parameters (laser beam position, laser power and spot size) on the instability of double-layer thermocapillary convection are also studied. The calculation results show that the adjustment of laser power and spot size can significantly change the convective vortex structure in the spot area and weaken the vibration amplitude of temperature wave. Under certain working conditions, the temperature fluctuation range near the heat source changes significantly from 0.7 K to 0.1 K. The amplitude of temperature oscillation decreases first and then increases with the increase of spot size. The adjustment of the laser position can affect the position of the local convection vortex in the liquid layer, and then change the convection intensity on both sides of the laser position, so as to realize the control of the oscillating and unstable flow in the local region, the effective control of thermocapillary convection of double-layer fluid can be realized through the reasonable selection of photothermal effect parameters.
