Abstract

This chapter introduces some of the basic concepts in heat transfer, fluid mechanics and numerical solution methods. Since laser machining is a thermal process, an understanding of issues in conduction heat transfer, convection heat transfer, radiation heat transfer, and fluid mechanics is necessary in order to develop process models which relate the operating parameters of the laser, positioning system, and gas jet to the resulting erosion front geometry and temperature distribution. Also, in some situations the laser machining problem is difficult to solve analytically; in these cases, a numerical approach must be taken. Some basic concepts in finite difference and finite element methods are also introduced.
