“…Ideally, analysts only spend time on analysis work rather than these repetitive preprocessing tasks. A rapid parameter configuration method for two dimensions simplified model was generated for pipe-net calculation [33], and the results obtained are in good agreement with the results of the three-dimensional model simulation [34]. erefore, in order to effectively complete the design cycle and improve the design quality, it is necessary to establish a reasonable modeling technology to ensure that the CAD model of the design can adapt to the subsequent simulation, and the analysis results of the numerical simulation can be quickly fed back to the modification of the CAD model.…”

Product modeling has been applied in product engineering with success for geometric representation. With the application of multidisciplinary analysis, application-driven models need specific knowledge and time-consuming adjustment work based on the geometric model. This paper proposes a novel modeling technology named computer-aided design-supporting-simulation (CADSS) to generate multiphysics domain models to support multidisciplinary design optimization processes. Multiphysics model representation was analyzed to verify gaps among different domain models’ parameters. Therefore, multiphysics domain model architecture was integrated by optimization model, design model, and simulation model in consideration of domain model’s parameters. Besides, CADSS uses requirement space, domain knowledge, and software technology to describe the multidisciplinary model’s parameters and its transition. Depending on the domain requirements, the CADSS system extracts the required knowledge by decomposing product functions and then embeds the domain knowledge into functional features using software technology. This research aims to effectively complete the design cycle and improve the design quality by providing a consistent and concurrent modeling environment to generate an adaptable model for multiphysics simulation. This system is demonstrated by modeling turbine blade design with multiphysics simulations including computational fluid dynamics (CFD), conjugate heat transfer (CHT), and finite element analysis (FEA). Moreover, the blade multiphysics simulation model is validated by the optimization design of the film hole. The results show that the high-fidelity multiphysics simulation model generated through CADSS can be adapted to subsequent simulations.

Manually preparing the data for the analysis of the calculation of a pipe network of air-cooled turbine blades is inefficient. In this paper, a method to adaptively divide the blade model and extract data of the flow units is proposed. In this method, the topological lines of the flow channels for the calculations of the pipe network were extracted based on the simulatedfluid flow. The abstracted lines of the fluid flow area were used to replace the manual interpretation of expertsto realize the adaptive division of the flow units and to understand the connection relationship of the units and the layout of the spatial network. In addition, by establishing a basic flow unit library and constructing a specific algorithm, we quickly extracted the data from the typical flow units. Finally, the proposed method and algorithm were verified with a representative case study. The results illustrated that our method could cut down the pre-processing in the calculation of the pipe network of air-cooled turbine blades to several minutes from the several hours required for the manual method while providing reliable quality.
