AbstractJapan Aerospace Exploration Agency (JAXA) is developing a practical Experimental Fluid Dynamics and Computational Fluid Dynamics (EFD/CFD) integration system called the Digital/Analog Hybrid Wind Tunnel(DAHWIN), where ‘Digital’ and ‘Analog’ denote CFD and EFD (or wind tunnel), respectively. The aim of thissystem is to improve effectiveness, accuracy, and reliability of wind tunnel tests by jointly utilizing CFD as well as some advanced techniques for the EFD/CFD integration. For the development of the Digital Wind Tunnel(DWT), both features of high-speed performance and high degree of accuracy must be accomplishedsimultaneously for realizing the timely use of the DAHWIN system and high-fidelity wind tunnel data corrections. In this paper, several functions of the DWT and a newly-developed fast CFD routine for the DWTare introduced.
