Two-dimensional gas-phase temperature measurements using phosphor thermometry

Thermographic Phosphors for High Temperature Measurements: Principles, Current State of the Art and Recent Applications

“…This system allows the cross checking of temperature using the two methods, and also extends the dynamic range of measurement [35]. Similar two mode response systems have been reported by Omrane and Hasegawa [36]. …”

“…Hasegawa et al [36] investigated the intensity ratio of YAG:Dy for such measurements with the ultimate aim of measuring the gas temperatures in an operational engine.…”

Characterisation of the luminescence properties of BAM:Eu2+ particles as a tracer for thermographic particle image velocimetry

“…In recent years, there have been several studies using thermographic phosphors for gas thermometry [1][2][3][4][5][6][7][8][9][10][11][12][13], and different phosphors have been used. Some important luminescence properties of these phosphors are indicated in Table 1.…”

On the design of phosphors for high-temperature thermometry

“…Nevertheless, measurements can be made up to at least 1400 1C with this phosphor (Goss et al [5]). This is sufficient for many applications but recently the author and co-workers, along with others, have begun to look at the possibility of using phosphor particles as flow borne temperature sensors in flames (Rabhiou et al [6], Hasegawa et al [7]). In such flows temperatures in excess of 2000 1C can occur and this leads one to wonder if phosphors even better than YAG:Dy can be found or indeed designed.…”
