Flow visualization is used for getting a quick qualitative overview of the flow around objects such as vehicles or airplanes in large wind tunnels.
Flow Visualization around a Rotating Body in a Wind TunnelSelf-excited vibrationflow visualizationcolor schlierentuftThe rotational behavior of capsule-shaped models is investigated in the transonic wind tunnel of JAXA. A special support is developed to allow the model to rotate around the pitch, yaw...
The proposed paper presents flow visualization performed during experiments conducted on a full-scale F/A-18 aircraft in the 80- by 120-Foot Wind-Tunnel at NASA Ames Research Center. This investigation used both surface and off-surface flow visualization techniques to examine the flow field on th...
The paper presents results of flow visualization and mass transfer studies for fully developed turbulent flow of air in a square section wind tunnel with repeated chamfered rib roughness on the bottom of the tunnel (rib head chamfer angles of -15°, 0°, and 15°; relative roughness pitch p...

2. Boundary layrer visualization with vapor-screen method. Supersonic air-intake is one of the most important components to realize the supersonic/hypersonic air-breathing engines. A mach 3 intake was designed and tested with the supersonic wind tunnel. In this study, several flow visualization ...
Flow visualization was conducted under various conditions using a simple room model and showed the basic flow characteristics at the inlet opening. Wind tunnel tests using a three-storey apartment building model with a movable test room were conducted to investigate the inflow direction and the air...
tunnel with three different Reynold numbers 2600, 3400 and 4600 based on tube transverse pitch. Both CFU andCFDconfiguration was studied as depicted inFig. 17a and b respectively. By using the die injectionflow visualizationtechnique, flow pattern around the tubes and VGs were reported. They ...
In order to show whether Rayleigh scattering from gas molecules of a wind tunnel flow field is applicable for the acquisition of density data in the case of aerodynamically relevant flow problems, initial tests in a Ludwieg Tube at a Mach number 6.8 have been performed. Based on the experienc...
