The Study on the Laser Ignition Model and Its Analytic Solution of Solid Energetic Materials

摘要

The intensive transient non-Fourier heat conduction caused by high power laser ignition and the classical heat conduction are analyzed. It indicates that laser ignition has a different heat transfer mechanism from the common case. From the point of view of mathematics, a wave equation is corresponding to this kind of transient heat conduction, while a diffusive equation is to classical problem. The analytic solution is also worked out at the given boundary and initial conditions.
