A quantitative and three-dimensional density measurements of high-speed and unsteady flow including shockwaves by LICT method

本研究旨在捕捉及分析放电冲击波所引发的三维流场复杂现象。将激光干涉计算机层析成像（LICT）技术应用于高速、非定常流场（包括激波）中，实现了密度的三维定量测量。应用LICT方法研究了两个倾斜圆喷管喷出激波的流场以及圆喷管喷出激波与圆杆的相互作用。

The purpose of this research is capturing and analyzing the complex phenomena on three-dimensional flow field induced by discharging shockwaves. Laser Interferometric Computed Tomography (LICT) method using interferometer with laser light source is applied to high-speed and unsteady flow field including shock waves for realizing quantitative and three-dimensional density measurements. LICT method is applied to flow fields induced by discharging shockwaves from inclined two circular nozzles and interaction between discharging shockwave from a circular nozzle and circular rod.
