车辆外部空气动力学数据集
收藏资源简介:
该数据集由大众汽车公司在车辆开发过程中收集的空气动力学仿真组成,包含来自五个不同车辆项目的32个基线车辆几何体及其变化,反映了车辆开发过程中遇到的多样化自由形式修改。数据集共有343个样本,其中274个用于训练,69个用于测试。所有仿真均采用OpenFOAM进行的分离涡模拟。数据集旨在为评估数据驱动代理模型在预测任意输入几何形状的阻力系数方面的性能,以解决车辆开发中气动优化问题。
This dataset consists of aerodynamic simulations collected by Volkswagen AG during vehicle development processes. It contains 32 baseline vehicle geometries and their variants from five distinct vehicle projects, reflecting the diverse free-form modifications encountered during vehicle development. The dataset has a total of 343 samples, with 274 allocated for training and 69 for testing. All simulations are detached eddy simulations performed using OpenFOAM. This dataset is intended to evaluate the performance of data-driven surrogate models for predicting drag coefficients of arbitrary input geometries, thereby addressing aerodynamic optimization challenges in vehicle development.
