Optimization of confocal laser induced fluorescence in a plasma.
Laser Induced Fluorescence (LIF) provides measurements of flow speed, temperature, and density of ions or neutrals in a plasma. Traditionally, a LIF measurement requires two ports on a plasma device; one for laser injection and one for emission collection. Proper alignment of LIF optics is time consuming and sensitive to mechanical vibration. We describe a confocal configuration for LIF that re...
متن کاملMixing of the Immiscible Liquids in the Entrance Region of a T-Type Chamber Using Laser Induced Fluorescence (LIF) Method
A Laser Induced Fluorescence technique (LIF) has been used to study the mixing behavior of two emerging streams in a T-Type mixing chamber. A mixing index on the basis of digital image light intensities is calculated. It has been shown that averaging over more than 800 images leads to a stable mixing index calculation. Moreover, the effect of equal and un-equal flow rates on the mixing behavior...
متن کاملLaser-Induced Fluorescence Imaging
Fluorescence imaging is a tool of increasing importance in aerodynamics, fluid flow visualization, and nondestructive evaluation in a variety of industrial circumstances. It is a means for producing two-dimensional images of real surfaces or fluid case-sectional areas that correspond to data on properties such as temperature or pressure across the surfaces. This article discusses three major fl...

متن کاملMicroscale Laser-Induced Fluorescence Method for Non-Intrusive Temperature Measurement
Ratiometric Laser Induced Fluorescence (LIF) Thermometry is applied for temperature measurements in a ‘T’ junction, using microscale visualization methods. Rhodamine B (RhB) and Rhodamine 110 (Rh110) are used as the temperature-dependent and temperature-independent dye, respectively. The temperature responses of the two dyes were carefully measured for different concentrations. A novel normaliz...
