Abstract: Based on WENO reconstruction,a high-order (at least third order) moving mesh kinetic scheme is presented for compressible flows.It employs the frame of remapping-free ALE-type kinetic method to discrete Euler equation.Adaptive moving mesh approach is used to move meshes.Kinetic flux evolution is used to construct numerical fluxes in order to achieve their time-accuracy.Numerical results demonstrate accuracy and robustness of the scheme.

Key words: WENO scheme, ALE method, gas kinetic scheme, adaptive moving mesh method
