| Research Abstract |
In this study, numerical methods for nonlinear fluid interaction problems were constructed based on the secondary conservative convection scheme and the JFNK(Jacobian-Free NewtonKrylov) method. Specifically,(1) the nonsegregated numerical method for incompressible flows,(2) the secondary conservative finitedifference scheme for compressible flows,(3) the secondary conservative finitedifference convection scheme for moving grids,(4) the high-order accurate compact finitedifference scheme for incompressible flows,(5) the hybrid scheme of the shock capturing method and the secondary conservative finitedifference scheme, and(6) the numerical method for nonNewtonian fluid in turbulent boundary-layer flow, were constructed.
