abstract = {<p style="text-align: justify;">The purpose of this article is to summarize our recent progress in high-order
and high accurate CFD methods for flow problems with complex grids as well as
to discuss the engineering prospects in using these methods. Despite the rapid development of high-order algorithms in CFD, the applications of high-order and high
accurate methods on complex configurations are still limited. One of the main reasons which hinder the widely applications of these methods is the complexity of grids.
Many aspects which can be neglected for low-order schemes must be treated carefully
for high-order ones when the configurations are complex. In order to implement high-order finite difference schemes on complex multi-block grids, the geometric conservation law and block-interface conditions are discussed. A conservative metric method is
applied to calculate the grid derivatives, and a characteristic-based interface condition
is employed to fulfil high-order multi-block computing. The fifth-order WCNS-E-5
proposed by Deng [9, 10] is applied to simulate flows with complex grids, including
a double-delta wing, a transonic airplane configuration, and a hypersonic X-38 configuration. The results in this paper and the references show pleasant prospects in
engineering-oriented applications of high-order schemes.</p>},
