Abstract
This technical note provides a summary of work carried out to improve, verify and validate the Trident UNDEX Interface computer code for DRDC. The improvements included the incorporation of a capability to automatically generate, with minimum input from the user, input files for Vast-USA, and a state-of-the-art survey of potential flow methods for calculating the dynamics of near-field UNDEX gas bubbles. The verification and validation focused on the recently developed tightly coupled Vast-USA interface. In total six different problems were investigated for: (1) comparison with the loosely coupled Vast-USA Interface; (2) comparison with LS-DYNA; (3) comparison with experiment; and (4) consistency with units. Recommendations are made for: (1) further improvements to the Trident UNDEX Interface, including the incorporation of a boundary element technique for modeling nearfield UNDEX bubble dynamics; and (2) further verification and validation studies.
