提出了一种基于重构修正的隐式大涡模拟求解方法。该格式允许在包含弯曲边界元的非结构化网格上求解非定常Navier-Stokes方程的高阶精确解。采用显式和隐式时间格式，隐式方法依赖于拟牛顿- gmres方法和三阶单对角隐式龙格-库塔（SDIRK）格式。Taylor-Green涡旋问题的ILES计算结果表明，与低阶近似相比，当前的高阶格式可以在同等计算成本下提供更精确的解。在M = 0:2和Re = 60的情况下，对SD7003翼型进行了初步研究。000例表明，目前实施的CPR方案能够解决航空航天应用中的复杂、不稳定、过渡和湍流问题。
An implicit large eddy simulation (ILES) solver is presented using the novel correction procedure via reconstruction (CPR) scheme. This scheme allows for high-order accurate solutions of the unsteady Navier-Stokes equations on unstructured meshes containing curved boundary elements. Explicit and implicit temporal schemes are used, with the implicit method relying on a quasi Newton-GMRES approach with a third order singly diagonal implicit Runge-Kutta (SDIRK) scheme. Results for ILES of the Taylor-Green vortex problem show that the current high-order schemes can provide more accurate solutions at equivalent computational cost to the lower order approximations. Preliminary results for ow over an SD7003 airfoil at M = 0:2 and Re = 60;000 show the current implementation of the CPR scheme is capable of solving complex, unsteady, transitional and turbulent ows for aerospace applications.
