Method to eliminate the interference of model support in automotive wind tunnel
摘要
Abstract
Using the traditional experience of mirror method for reference, a method to eliminate the aerodynamic interference of model support in automotive wind tunnel is provided in this paper.Two tests have been done with car model linked or separated from support of six-components balance.Through the two tests,the sum of aerodynamic forces on the car model and the interference of support was acquired.To reduce the interference of the support with the car model, numerical simulations of the wind tunnel tests have been done by commercial CFD code at the same time.Through CFD, the aerodynamic interference of the support with all kinds of model were got.After modified the results, the interference results have been transformed into correction data of model support in automotive wind tunnel.The data without interference of support could get easily.This research combined wind tunnel tests and numerical simulations.The results indicated that these two ways, which could validate and supplement each other,could solve the engineering problem of eliminating the interference of model support in automotive wind tunnel test.关键词
