摘要 本文提出了一种用于解决流体在球内以低马赫数流动问题的半离散Jacobi-球面调和谱格式,并证明了它的稳定性和收敛性.所用技巧也可应用于球形区域上其它非线性问题. A semi discrete Jacobi-spherical harmonic spectral scheme is proposed for the fluid flow with low Mach number in a ball. Its stability and convergence are proved. The techniques in this work are also applicable to other nonlinear problems with spherical geometry.
