Flow visualization techniques and examples pdf
Application of Flow Visualization Technique to Aircraft Wind Tunnel TestingFlow visualization or flow visualisation in fluid dynamics is used to make the flow patterns visible, in order to get qualitative or quantitative information on them. Flow visualization is the art of making flow patterns visible. Most fluids air, water, etc. Historically, such methods included experimental methods. With the development of computer models and CFD simulating flow processes e. In experimental fluid dynamics , flows are visualized by three methods:. In scientific visualization flows are visualized with two main methods:.
Fluid Flow Visualization
Wind tunnel test and computational fluid dynamics have been used for the aerodynamics design of the aircraft. Especially, in the case of wind tunnel test, the scale model which has various sensors inside has been installed in the wind tunnel, and 6 component force and moment, surface pressure and hinge moment of the control surface have been measured in the wind tunnel test. It is indispensable for the aerodynamics design to understand the flow phenomenon around the aircraft correctly. Therefore, the flow visualization techniques have been utilized in the aircraft development wind tunnel test since a long time ago. This paper summarizes the typical examples of traditional and latest flow visualization techniques in the aircraft development wind tunnel test. Also, the expected flow visualization technique in the future is described in this paper.
