SUMMARY We present a detailed comparative study of three conservative schemes used to transfer interface loads in fluid–solid interaction simulations involving non-matching meshes. The three load transfer schemes investigated are the node-projection scheme, the quadrature-projection scheme and the common-refinement based scheme. The accuracy associated with… (More)

Simulation of solid rocket motors requires coupling physical models and software tools from multiple disciplines, and in turn demands advanced techniques to integrate independently developed physics solvers eectively. In this paper, we overview some computer science components required for such integration. We package these components into a software… (More)

We describe simulations of solid rocket motors that involve coupling between the core fluid flow, the structural response of the propellant and case, and the combustion of the propellant. A partitioned predictor-corrector algorithm is employed to treat the fluid-structure interaction. The combustion rate of the propellant is coupled to the fluid flow via an… (More)

We describe our numerical method for three-dimensional simulations of solid rocket motors in which the internal gas dynamics, the combustion of the propellant, and the structural response are fully coupled. The combustion zone is treated as a thin layer using appropriate jump conditions, and the regression rate is determined using a nonlinear dynamic… (More)

We describe and present results from GEN2, the second generation three-dimensional solid rocket motor simulation package developed at CSAR. The internal gas dynamics, propellant combustion, and structural response are fully coupled. In addition to several test cases, we simulate propellant slumping at a joint slot due to uneven gas pressure loads in the… (More)

Directed at the precision-decreasing problems like abrasion and slippage which occur in the roller for measuring continuous-casting slab length, a technology of edge detection for CCD (charge coupled device) digital image was adopted that fulfilled fixed-length cutting control at the first stage and dynamic tracing of casting speed. With hydraulic pressure… (More)
