We propose a random projection method for numerical simulations of hyperbolic conservation laws with stiff source terms arising from chemically reactive flows: In this problem, the chemical time scales may be orders of magnitude faster than the fluid dynamical time scales, making the problem numeri

## 25+(1 -L)u,=O aty2=0 dyz to determine J,, we ensure that the zero-order solution does not have a boundary layer. In other words the higher-order terms will be of the order-of s/(1 -1) and, thus, will be small. Now, condition (8) is mathematically equivalent to d2u 2 = 0 dyt at yz = 0. (9)
This paper reports on the numerical implementation of a convergent scheme solving a general class of nonlinear Boltzmann-like equations for reacting fluids. The scheme is tested on a model of space-homogeneous multicomponent gas with binary chemical reactions. Although the model cannot be solved exa
