Multi-scale Modeling of Solid Fuel Ramjet Combustion with Embedded Reactive Metal Particles
Abstract
Solid Fuel Ramjet (SFRJ) combustion with or without embedded nano reactive metal particles in the solid fuel is a major modeling challenge as all the physics occur near the wall and proper prediction of the flow features will need coupling of finite-rate, heat/mass transfer and phase change of the solid fuel as well as fine grid resolution. Fine wall-resolved modeling will be computationally intractable and therefore, we will develop a novel wall-modeled multi-scale model to make the simulations feasible. Preliminary studies using SFRJ have demonstrated some of the key areas for further studies. New models will be designed to incorporate features in amodular forms. Further code acceleration will be achieved using Graphical Processing Unit (GPU) based methods on top of its existing parallel strategy to get the code ready for cost-effective design studies in next generation desktop computers. The model will be implemented within our code with constraints to be backward compatible as this code is currently deployed at various Federal research laboratories. Approved for public release.
