Simultaneous measurement of velocity and temperature field of high temperature jet using thermographic phosphor particles
In order to overcome existing complicated and costly simultaneous measurement system, an inexpensive and simple measurement system was suggested to measure the temperature field and velocity field at high temperature. The manganese-activated magnesium fluorogermanate (Mg4FGe6:Mn, MFG) which is one of thermographic phosphor with luminescence characteristic of excitation at 385 nm wavelength and ...

A mathematical model for gas-liquid flows subject to mass transfer and chemical reactions is presented. It is shown that bubble-induced buoyancy resembles natural convection and can readily be incorporated into an incompressible flow solver by using an analog of the Boussinesq approximation. Extra transport equations with nonlinear source terms are introduced to describe the evolution of scalar...
متن کاملThermographic laser Doppler velocimetry.
We propose a point measurement technique for simultaneous gas temperature and velocity measurement based on thermographic phosphor particles dispersed in the fluid. The flow velocity is determined from the frequency of light scattered by BaMgAl10O17:Eu2+ phosphor particles traversing the fringes like in conventional laser Doppler velocimetry. Flow temperatures are derived using a two-color rati...
