We presented a mathematical model of dual-pulse laser ignition in a turbulent flow taking into account detailed combustion chemistry and non-equilibrium plasma dynamics in a frame of a three-temperature plasma model. To account for turbulence we use four semi-empirical models: k ε model, RNG k ε model and SST model. Preliminary results showed a possibility of reliable laser ignition in a turbulent flow using a dual-pulse approach. We have found that to get a better ignition probability in a turbulent flow we need to increase the initial number density of electrons seeded by the first ultra-violet pulse. k-ω--.
