CFD high-order accurate scheme Jacobian-Free Newton Krylov method

•We applied JFNK method to CFD high-order accurate scheme.•We formed a nonlinear type of preconditioner.•A high efficiency precondition matrix for high-order accurate scheme was formed.•Test cases shown that wall time was saved half with JFNK method. High-order accurate scheme for Computational Flui...
