To achieve second-order spatial accuracy in CFD solver on unstructured grid, reconstruction method such as Green-Gauss method or a least square approximation is used with a slope limiter. However Barth-Jespersen limiter, which is generally applied in the solvers on unstructured grid, has disadvantage for convergence to steady state solution and Venkatakrishnan limiter also has problem that second-order accuracy is lost on irregular grid. In this paper, a new slope limiter is proposed and applied to unstructured fast flow solver FaSTAR to overcome such problems.
