review text: An implicit algorithm for computing viscous flows in chemical nonequilibrium is presented. Emphasis is placed on the numerical efficiency of the time integration scheme, both in terms of per-iteration workload and overall convergence rate. In this context, several techniques are introduced, including a stable, \({\mathcal O}(m^2)\) approximate factorization of the chemical source Jacobian and implementations of \(V\)-cycle and filtered multigrid acceleration methods. A five species-seventeen reaction air model is used to calculate hypersonic viscous flow over a cylinder at conditions corresponding to flight at 5 km/s, 60 km altitude and at 11.36 km/s, 76.42 km altitude.
