This Small Business Innovation Research Project will determine the advantages and disad-vantages of fibrous/polymeric composite materials over traditional material (steel) for retrofitting key civilian facilities against terrorist bomb attack. Retrofit techniques we will evaluate are: strengthening fully and partially exposed columns with composite wraps or shells, masonry walls with bonded comp ...

Toward understanding how turbulent mixing with air of detonation products of fuel-rich explosives results in further combustion of the detonation products and, therefore, enhanced lethality, we first consider an exothermic reaction of a premixed fuel/oxidizer in a closed vessel in the limit of zero Mach number and infinite Reynolds, Peclet, and Damkohler numbers. To help elucidate the main mechan ...

This proposed work aims at deeloping two major new innovqative capabiliities for the High-Order Godunov (HOG) technology. The first new capability is in the area of low Mach number problems; new code based on the projection method scheme will be developed for complex 3D multiphase flow fields, in particular, the post explosion cloud rise phenomenon includin gparticle transport. The second new ca ...

Environments created from a nuclear event can have a great impact upon the operation of military forces on the battlefield. It is imperative that the associated nuclear effects are portrayed in an environment such as Dirstributed Interactive Simulation (DIS) so that changes canbe made during the weapon system design process to mitigate nuculear effects. These effectscan be extended to other appl ...
