Temperature and number density measurement in non-uniform supersonic flowfields undergoing mixing using toluene PLIF thermometry

Abstract: visualization and quantification of many flow properties, including scalar concentration and temperature measurements, and it has been long used in both low-and highspeed flows. PLIF imaging based on a variety of tracers has been considered through the literature [1]. Historically, acetone and 3-pentanone [2, 3] have been widely used for scalar and temperature imaging, and more recently, naphthalene [4,5], krypton [6], 1-methylnaphthalene [7], and anisole [8] have been utilized in a variety of applications.Tol… Show more

“…PLIF images). 57 In the PLIF images of figure 8, the mixing portion of the shear layer (E, H and K) is rendered as the high PLIF signal portion between the core of the jet and the post-shock region (both low PLIF signal regions). In some sense, this feature corresponds to the OH reacting layers presented in figure 4.…”

“…An account of the design and operation of this facility is given by Heltsley et al; 58 recent modeling efforts of this facility have been attempted by Örley et al 59,60 A more detailed accounting of the operation and calibration of the facility to produce the desired conditions used in this studies are also presented elsewhere 27,56,57,61 and are thus not repeated here in detail. The operational principle and a theoretical analysis of the performance of an expansion tube to generate high-enthalpy supersonic and hypersonic flows can be found in the seminal work of Trimpi.…”
