Research Abstract

A method for quantitative imaging for temperature in the rarefied gas flow has been developed. The flow field is visualized by planar laser-induced fluorescence (PLIF) of iodine molecules seeded in carrier gas. Iodine molecules have many absorption lines in visible region and radiate intense fluorescence. The fluorescence intensity is proportional to the number of molecules in the energy level excited by the laser beam. From the dependence of this number on the temperature, the local temperature can be decided from the ratio of the fluorescence intensities of two visualized images which are obtained by irradiations of laser beams with different wave length. This method allows to image the two-dimensional temperature distribution of the flow field by means of a laser sheet and a high sensitive vidicon camera. This method is applied to the temperature measurement of the flow field of a su personic free jet in which temperature varies drastically. It is found that the temperature distribution of the jet measured by P(16)/R(18) [514.720 nm] and P(26)/R(28) [514.942 nm] absorption lines in the transition of B(v'=43) X(v"=0) agrees well the theoretical one.
