Implementation of two-dimensional time accurate flow simulation on moving mesh exploiting mesh rupturing

A two-dimensional dynamic moving mesh algorithm is implemented for simulating aerodynamic oscillating airfoils. The airfoil is inserted into a uniform unstructured background mesh by exploiting an new technique named mesh rupturing, which allows for significant geometry movement without grid regeneration or interpolation between grids. Then unsteady flow simulation results are presented and validated by several test cases. Previous methodologies for unsteady flow simulation are listed and compared, advantages and disadvantages of the new mesh technique are discussed and advice for further research as well.
