What is A Mathematical Model for Lean Hydrogen-air-steam Mixture Combustion in Closed Vessels about?
The lean hydrogen-air-mixture combustion model described in this paper accounts for nonadiabatic, axisymmetric, buoyant flame propagation in a sphere or a cylinder. Turbulent burning velocity effects and heat losses associated with fan-stirred mixtures, equipment obstructions, and/or a water spray in the vessel are explicitly included in the model. Flame quenching and post-combustion cooldown are also modeled. Calculated results are compared with data from a variety of experiments conducted in vessels ranging in volume from 5 to 2,000 m 3. Comparisons with pressure data recorded during the accidental hydrogen deflagration in the Three Mite Island Unit 2 reactor building are also presented. Results indicate that peak pressures and burn times can be simulated quite well in many cases without using any arbitrarily adjusted parameter values. In other cases, such as the intermediate-scale cylindrical vessel tests, the nominal flame surface area had to be increased by a factor of 2-3 to achieve good agreement.
