Parameterization rapid three-dimensional modeling and order reduction analysis method for water cooling pipeline with bent pipe

The invention discloses a parameterized rapid three-dimensional modeling and order reduction analysis method for a water-cooling pipeline with a bent pipe, and relates to the field of parameter analysis of water-cooling pipelines. According to the invention, the research on the influence of the flow resistance of water-cooling pipelines with different structures and bent pipes is converted into the research on the influence of different bent pipe angles Angle (beta) and relative curvature radius (R/D0) on the flow resistance; secondly, mathematical modeling is carried out on the water cooling pipelines with different pipe bending angles and relative curvature radiuses; based on the pipeline structure, a finite volume model is built, and finite element simulation analysis is carried out; and finally, extracting a flow-pressure drop response curve of the fluid in the pipeline, generating an ROM reduced-order model, and realizing rapid calculation of the pressure drop under different working conditions.
