论文摘要
我们采用双探针1-D FS/PS杂交旋转相干性反stokes拉曼光谱，以研究气相诊断的同时温度，压力和O2/N2测量。双探针HRCARS技术允许从时间和频域进行同时测量。提出了一种新颖的测量压力方法，该方法提供了高精度（<1％）和精度（0.42％）。该技术首先在腔室中以一系列压力（1-1.5 bar）证明。该技术显示出在层状和湍流条件下撞击表面上的N2射流产生的1D压力梯度的令人印象深刻的能力。该技术显示能够解决从动能转换到压力的单发压梯度（0.04 bar/mm），并从层流和湍流混合中解析特征性的O2/N2结构。
We employ dual-probe 1-d fs/ps hybrid rotational coherent anti-Stokes Raman spectroscopy to investigate simultaneous temperature, pressure, and O2/N2 measurements for gas-phase diagnostics. The dual-probe HRCARS technique allows for simultaneous measurements from the time and frequency-domain. A novel approach for measuring pressure, which offers high accuracy (<1%) and precision (0.42%) is presented. The technique is first demonstrated in a chamber for a range of pressures (1-1.5 bar). This technique shows an impressive capability of resolving 1-d pressure gradients arising from a N2 jet impinging on a surface, both in laminar and turbulent conditions. The technique is shown to be capable of resolving single-shot pressure gradients (0.04 bar/mm) originating from kinetic energy conversion to pressure, and resolves characteristic O2/N2 structures from laminar and turbulent mixing.
