Abstract
Experimental measurement and numerical simulation are employed to study the effects of laser irradiation on aluminum alloy tank containing water. Firstly, by analyzing the surface pictures and measuring the temperature histories, the effects of water on the ablation of aluminum alloy plate irradiated by I 053 nm pulsed laser are investigated. The results show that heat conduction and convection play a very important role in the ablation of the aluminum alloy plate. When the tank is empty, the aluminum alloy plate is melt through after eight laser pulses irradiation. And when the tank is filled with water, the aluminum alloy plate has not been melt through after ten laser pulses irradiation. Then, a numerical model is presented to calculate the temperature distribution of the aluminum alloy tank, and the dimension of the region that has melted is obtained. The difference between the numerical result and the experimental result is not apparent when the tank is empty, but when the tank is filled with water the difference is a little large. The reason is that the natural convection and boiling of water are not considered in the numerical model.关键词
