In this paper, a multidimensional unstructured‐grid computational plasma aerodynamics methodology is developed for pulsed wave devices, with emphases on nonequilibrium effects and laser‐induced physics. The present numerical model couples the Navier‐Stokes equations, three‐temperature energy equations, finite‐rate chemistry model and ray‐tracing model with radiative energy absorption using realistic absorption coefficient formulation. With the model, the focused laser beam creates high energy concentration at focal point on aluminum surface and causes the ionization of aluminum, which starts the air plasma. Laser lightcraft designs of Myrabo, using pulsed laser as the energy source, are selected for numerical simulation and data comparisons.
