Abstract

Based on the Reynolds-averaged Navier-Stokes equations and cross-grid technology, this paper adopts the second-order MUSCL-Roe scheme and SA turbulence model to simulate two kinds of high-lift configurations from HiLiftPW-3. To validate the paper's numerical methods, the grid-convergence and aerodynamic characters for high-lift configuration are simulated. The comparison with the experimental data of pressure and aerodynamic force from JAXA (Japan Aerospace eXploration Agency) shows that, before reaching the stall angle, the aerodynamic coefficients of the numerical simulation and Cp distribution are highly anastomosed with the experimental data, providing a preferable simulation of the aerodynamic characters of dispersion from the variation of local configurations. The paper's numerical methods are well applicable to the typical high-lift configuration and could provide technological support for the aerodynamic design of civil plane in low-speed configuration.

Key words： high-lift configuration; numerical simulation; grid convergence; aerodynamic characteristic; pressure distribution
