희소점 표현법을 이용한 2차원 오일러 방정식의 수렴 가속화

Convergence Acceleration of 2D Euler Equation through Sparse Point Representation (SPR) Method

초록

Sparse Point Representation (SPR) based on interpolation wavelet is implemented for the purpose of convergence acceleration of time-marching problem. In solving Euler equation, SPR reconstruct the grid points at each time step. This grid re-adaptation through SPR allows huge reduction of computation time without losing accuracy. Moreover, application of the SPR to Navier-Stokes equation solver may improve computational time and memory efficiency.
