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.
I would like to thank Dr. Steve Karman for his guidance and patience during the research. Also, I would like to thank Dr. James Newman for his advice in completing the work, Jianfeng Yan for his time helping me in the discussion and Arash Ghasemi for the help to complete this document.
