High-precision 2D surface phosphor thermometry at kHz-rates during flame-wall interaction in narrow passages
Anthony O. Ojo, David Escofet-Martin, Brian Peterson
This work demonstrates high-speed 2D wall temperature measurements occurring during flame-wall interaction (FWI) within a narrow channel. Such measurements are essential to underst…
Revisiting N-N collisional linewidth models for S-branch rotational Raman scattering
Mark Linne, Nils Torge Mecker, Christopher J. Kliewer +2
This paper presents an evaluation of two commonly accepted Raman linewidth models typically used to fit CARS model parameters to data; the Modified Exponential Gap (MEG) and the En…
Precise surface temperature measurements at kHz-rates using phosphor thermometry to study flame-wall interactions in narrow passages
Anthony O. Ojo, David Escofet-Martin, Christopher Abram +2
The thermographic phosphor ScVO4:Bi3+ is used to obtain time-resolved surface temperature measurements with sub-oC precision at 5 kHz. Measurements are used to study transient heat…
Ultrafast multi-photon excitation of ScVO:Bi for luminescence thermometry
David Escofet-Martin, Anthony O. Ojo, Brian Peterson
We demonstrate a multi-photon excitation (MPE) scheme for luminescence thermometry using ScVO:Bi. MPE is performed using a 37 fs Ti:Sapphire laser pulse centred at 800 n…
Experimental investigation of thermal boundary layers and associated heat loss for transient engine-relevant processes using HRCARS and phosphor thermometry
Anthony O. Ojo, David Escofet-Martin, Joshua Collins +2
Design of efficient, downsized piston engines requires an understanding of transient wall heat losses. Measurements of the spatially and temporally evolving thermal boundary layer…
Dual-probe 1-d hybrid fs/ps rotational CARS for simultaneous single-shot temperature, pressure, and O2/N2 measurements
David Escofet-Martin, Anthony O. Ojo, Joshua Collins +3
We employ dual-probe 1-d fs/ps hybrid rotational coherent anti-Stokes Raman spectroscopy to investigate simultaneous temperature, pressure, and O2/N2 measurements for gas-phase dia…
Optimising hybrid rotational femtosecond/picosecond coherent anti-Stokes Raman spectroscopy (HR-CARS) in nitrogen at high pressures and temperatures
Nils Torge Mecker, Trevor L. Courtney, Brian D. Patterson +4
We demonstrate the use of hybrid rotational femtosecond/picosecond (fs/ps) coherent anti-Stokes Raman spectroscopy (HR-CARS) as a technique for temperature measurements in nitrogen…
