摘要

PROBLEM TO BE SOLVED: To conduct fluid analysis wherein formulation is exponentially simple, as compared with stabilization finite element method.;SOLUTION: This stabilization bubble function finite element fluid analysis device 1 is composed of a data storage part 2, a data extracting part 3, a fluid behavior calculating part 5 and a display control part 6. A fluid information table comprising a fluid ID, the name of the fluid, known physical values (density, viscosity coefficient) and an initial fluid behavior value (analysis start flow velocity and analysis start pressure) for each fluid is stored in the data storage part 2. The data extracting part 3 selects, from the storage part 2, the fluid ID of a fluid used as an analysis object by operating an input device to extract the fluid name, the known physical values (density, viscosity coefficient) and the initial fluid behavior value (analysis start flow velocity and analysis start pressure) related to the selected fluid ID. The calculation part 5 calculates the behavior value of the fluid based on the Navier-Stokes equation. The control part 6 outputs the analysis result in the calculation part 5.;COPYRIGHT: (C)2005,JPO&NCIPI
