Coupled hydrodynamic-structural response analysis of piping systems. [LMFBR]
The report describes in detail the expansion of the ICEPEL code for the coupled hydrodynamic-structural response analysis of pipe-elbow loops to general piping systems. A generalized piping-component model, a branching tee junction, and a surge-tank model are introduced and coupled with the pipe-elbow loop model so that a general piping system under the effect of internally traveling pressure pulses can be analyzed hydrodynamically, as well as structurally. Optional capabilities are included in the generalized piping-component model so that it can be used in modeling pipe-flow area changes, valves, and heat exchangers. The options are: nine different axisymmetric exterior wall configurations, elastic-plastic exterior walls, interior rigid-wall simulation, and heat-exchanger tube-bundle model. The Implicit Continuous-Fluid Eulerian (ICE) differencing technique is used in the hydrodynamic part of the analysis; the Waves in Hysteretic Arbitrary Media (WHAM) finite-element scheme is used in the structural response part of the analysis. Sample problems that demonstrate the capabilities and limitations of the method are presented. The results are discussed and conclusions are made in connection with further development of the method. Detailed input-output instructions for the ICEPEL code use are also presented.
