激光钻孔技术是一种新的可行的、正在发展的岩石破坏方法。激光与岩石相互作用的统一建模方法是传热学中一个复杂的课题。根据能量守恒定律,建立了传热的基本方程。在液-气界面和液-固界面上分别简化了焓、导热系数和比热等主要参数。提出了激光打孔过程温度场的一般数学模型。利用伽辽金方法,对一个岩石激光钻孔实例进行了数值分析。
Laser drilling technology is a new feasible and developing method of rock destruction. The unified modeling method of laser and rock interaction is a complicated subject of heat transfer science. According to the energy conservation law, the fundamental equation of heat transfer is established. Some primary parameters such as enthalpy, thermal conductivity and specific heat are simplified respectively on the liquid-gas interface or the liquid-solid interface. The general mathematical model of temperature fields on laser drilling process is proposed. Using the Galerkin method, the numerical investigation of a practical example in laser drilling rock is analyzed.
