Abstract:
This paper presents a multi-dimensional high-order gas-kinetic scheme on moving mesh to simulate unsteady flows of freely falling plates or thin coins. The two-dimensional scheme has previously been successfully implemented on freely falling plates, where the rich dynamical behavior, such as fluttering and tumbling motion, was analyzed and the quantitative comparison has been provided between the experimental measurement and numerical computation. In the past several years, a three-dimensional gas-kinetic scheme on moving grid has also been developed to compute fluid problems with moving boundaries. In this work in progress paper, both the modified grid velocity and high-order gas-kinetic scheme are developed to improve the above gas-kinetic method, which is applied for simulating three-dimensional freely falling thin disks.
