@article{Cai2020HighlyDG, title={Highly dilute gas flows over an ellipse}, author={Shiying Cai and Chunpei Cai and Jun Li}, journal={Physics of Fluids}, year={2020}, volume={32}, pages={097104} }

This paper presents recent investigation results on free molecular flows over a diffusely or specularly reflective ellipse, by using the gaskinetic theory. A virtual density distribution along the a diffusely reflective surface is introduced to aid the investigations. Many local surface properties are obtained, including surface slip velocity, coefficients for pressure, friction, and heat flux. Global coefficients for aerodynamic forces and moments, mass center-force center distances, are also…
