Abstract:

CURRENT COROPUTER ANALYSIS OF BUBBLE-SUBMERGED STRUCTURE INTERACTION, DUE TO CONVENTIONAL WEAPONS, IS EXTREMELY RESOURCE INTENSIVE. THEREFORE, IT IS VERY DIFFICULT TO REPLACE FULL SCALE LIVE FIRE TESTING OF SUBMERGED STRUCTURE WITH SCALE TESTING OF SUBMERGED STRUCTURES AND COMPUTER ANALYSIS. THE GOAL OF THIS EFFORT IS TO DEVELOP AN ACCURATE AND EFFICIENT NON-REFLECTING BOUNDARY FOR EULERIAN HYDRODYNAMICS ANALYSIS PROGRAMS. THIS BOUNDARY WILL MAKE IT POSSIBLE FOR THE COIOPUTER ANALYSIS EFFORT TO CONCENTRATE ON THE IMPORTANT AREAS SUCH AS THE STRUCTURE. THIS EULERIAN NON-REFLECTING BOUNDARY WILL BE DERIVED FROM A LAGRANGIAN NON-REFLECTING BOUNDARY, SPECIFICALLY DOUBLY ASYZOPTOTIC APPROXIMATION .
