HiLiftPW-1～HiLiftPW-3数值模拟技术综述

An overview of HiLiftPW-1 to HiLiftPW-3 numerical simulation technologies

针对典型运输机高升力构型,源于DPW(Drag Prediction Workshop)系列会议,美国航空航天学会(AIAA)组织的高升力预测研讨会(High Lift Prediction Workshop,HiLiftPW)已经连续举办了3届(HiLiftPW-1~HiLiftPW-3)。HiLiftPW系列会议的主要目的是评估现代CFD技术模拟典型运输机高升力构型的能力,促进高升力构型的复杂流动机理研究,指明高升力构型数值模拟技术的研究方向。本文概述了HiLiftPW-1~HiLiftPW-3会议的基本情况及主要结论;介绍了历次HiLiftPW会议所采用的高升力构型及风洞试验情况;并从计算网格生成、计算方法与湍流模型、计算结果与试验结果的对比等方面总结了CFD验证与确认工作的进展;最后给出了进一步开展CFD验证与确认工作的思考与建议。

Following the success of Drag Prediction Workshop（DPW）series,AIAA has organized three rounds of High Lift Prediction Workshop（HiLiftPW）,especially for typical commercial transport aircraft.The main objectives of the workshops are to assess the numerical prediction capability of current generation CFD technology for high lift configuration,advance the understanding of high lift complicated flow physics,and identify the areas needing additional research.This paper outlines the basic information and main conclusions from HiLiftPW-1 to HiLiftPW-3,introduces the high lift reference models and related wind tunnel tests.The progress in the fields of CFD verification and validation is summarized,including grid generation,numerical method and turbulent model,and comparison between numerical results and experimental data.At last,provides some thoughts and suggestions on CFD verification and validation.
