Jan 2, 2019 · Shape optimization is a handy tool in the product-design cycle. This article discusses the different CFD-based shape optimization techniques.

CFD grid generation for a full airplane model is time-consuming and costly. Detailed CFD grids based on a computer-aided design (CAD) model can take several days to develop and validate. Gradient-based optimization requires accurate sensitivity analysis for all four steps of ASO.

Feb 5, 2025 · A simplified simulation model based on computational fluid dynamics (CFD) for the mass transfer in the distillation column is used and a corresponding shape optimization problem is formulated. The goal of the optimization is to increase the mass transfer in the column by changing the packing's shape, which has been previously used as criterion ...

Choosing the right mesh type is crucial for successful CFD simulations. Structured meshes offer efficiency and accuracy for simpler geometries, while unstructured meshes provide flexibility for complex shapes. Hybrid meshes combine the best of …

Body is part of surface of flow domain. The geometry of the flow domain is also computationally modeled (CAD). Shape of the flow domain usually considers the grid topology (this is especially true of structured grids). Extent of flow domain depends on choice of boundary conditions.

CFD topology optimization with Tosca Fluid has shown its strengths in several Ford CFD applications. Pressure drops have been reduced and flow uniformity and mass flow rates have been substantially increased. Nevertheless, the optimization can be further improved using a shape optimization for fine-tuning afterwards. 2.2 CFD Shape Optimization

In this paper, focus is put on shape optimization for aero- and hydrodynamic performance. Prominent examples are the internal thermo-fluid dynamics of compressors and turbines, the external aerodynamics of cars, the hydrodynamics of ship hulls and their propulsion systems as well as the fluid dynamics of mixers, valves, ducts and pumps.
