“…So any phenomenon is limited to being observed if only it occurs within the excited state period of the phosphor and the speed is essentially dependent on the camera frame rate (MHz). Combining both the fluorescence and phosphorescence techniques has shown to be successful [106,107] in understanding the breakup and mixing of liquid fuels at high pressure and temperature conditions similar to those in combustion chambers. Figure 34 shows the experimental setup of thermal imaging by the spectral method.…”

A concise review of the recent developments in some of the standard optical diagnostics applied for primary jet breakup studies has been presented here. Primary breakup is the core breakup of liquid jets and sheets into droplets upon its interaction with the ambient gaseous atmosphere. This phenomenon is encountered in various aerodynamic, fluid dynamic, and combustion situations. The imaging diagnostics reviewed here include photography, high-speed imaging, shadowgraphy, digital holography, ballistic imaging, jet core illumination, thermal imaging, Mie imaging, x-ray phase contrast imaging, and laser-induced fluorescence. The advantages and limitations of each technique, their success, and future developmental trend are discussed.

“…This model is based on a multistep decay process that takes into account the multiple decay probabilities that exist for polyatomic molecules, such as fluorescence, vibrational relaxation, and intersystem crossing. Bryant et al [43], Tran et al [44] and Hartwig [45] extended the model of Thurber to wider pressure and temperature ranges and tested the model accuracy.…”
