| Zusammenfassung: | Заглавие с экрана In this study, we investigated convection dynamics in a thin liquid layer subjected to local laser heating in the absence of the Marangoni effect. Using a 1 mm water layer with a glass substrate in contact with the water surface to suppress surface tension-driven flows, we examined pure buoyancy-driven convection mechanisms. Particle Image Velocimetry (PIV) and thermal imaging techniques were employed to visualize flow patterns and temperature distributions. Our results revealed characteristic thermal equilibrium after 80–100 seconds of heating and the formation of a hexagonal convection pattern with six distinct divergence points Текстовый файл |
