The Cylinder in Crossflow is a synthetic dataset involving unstable laminar flow past a vortex-generating cylinder, whose shedding pattern is known as the von Kármán vortex street. The governing equations for this system are the incompressible Navier-Stokes equations. The cylinder has a diameter of 1, and the free-stream velocity is 1. The kinematic viscosity $
u$ is varied such that the Reynolds number ranges between 100 and 400. Symmetric boundary conditions are applied to the top and bottom edges of the computational domain, while an open pressure boundary condition is used at the outlet. The solutions are obtained on an unstructured grid composed of 6384 quadrilateral elements.

背景概述

Cylinder in Crossflow是一个合成数据集，模拟圆柱体在不稳定层流中的涡流脱落现象（冯卡门涡街），基于不可压缩Navier-Stokes方程，雷诺数范围为100至400，使用非结构化网格计算。该数据集由桑迪亚国家实验室于2021年发布。
