MRI: Acquisition of High Speed Video Imaging System for Electromagnetic Shockwave Control and Shockwave-Boundary Layer Interaction Research at AAMU

本项目的目标是为亚拉巴马A M大学（AAMU）的马赫数4超音速风洞获得一个高速视频成像系统。该成像系统将使研究人员能够进行电磁冲击波控制和冲击波/边界层相互作用研究，这两项研究都需要捕捉冲击波的位置和极端热通量区域附近的运动，其中冲击波通常以1 kHz至20 kHz的频率振荡。AAMU超音速风洞是一个最先进的激波实验设施。该风洞设施可以在6x6 x18英寸的试验段内以4马赫的速度提供稳定的空气20秒。现有的风洞仪器包括支杆天平、光学成像纹影系统和计算机控制的48通道高速数据采集系统。然而，该风洞系统不具有任何高速成像能力，这对于超声速激波干扰研究是至关重要的。拟议项目将购买Vision Research公司生产的高速高分辨率数字视频系统Phantom V1210摄像机。它是超声速风洞设备的必备仪器。这将立即使研究电磁控制的激波和激波边界层相互作用使用AAMU？超音速风洞。

1337227DengThe objective of this proposal is to acquire a high-speed video imaging system for the Mach 4 supersonic wind tunnel at Alabama A&M University (AAMU). The imaging system will enable researchers to conduct electromagnetic shockwave control and shockwave/boundary layer interaction research, both require capturing the shockwave location and movement near the area of extreme heat fluxes where the shockwave is typically oscillating at 1kHz to 20 kHz frequency. The AAMU supersonic wind tunnel is a state-of-the-art facility for shockwave experiments. This wind tunnel facility can provide stable air at speed of Mach 4 for 20 seconds within 6x6x18 inch test section. The existing instrumentation for the wind tunnel includes a sting balance, an optical imaging Schlieren system and a computer controlled high speed data acquisition system with 48 channels. However, this wind tunnel system does not have any high speed imaging capability, which is critical to the supersonic shockwave interaction research. The proposed project will acquire a high-speed high-resolution digital video system, the Phantom V1210 camera, made by Vision Research. It is the necessary instrument for the supersonic wind tunnel facility. It will immediately enable the research in electromagnetic control of shockwave and shockwave-boundary layer interaction using AAMU?s Supersonic wind tunnel.
