Assessment and Application of Wavelet-based Optical Flow Velocimetry (wOFV) to Wall-Bounded Turbulent Flows
Alexander Nicolas, Florian Zentgraf, Mark Linne +2
The performance of a wavelet-based optical flow velocimetry (wOFV) algorithm to extract high accuracy and high resolution velocity fields from particle images in wall-bounded turbu…
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…
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…
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…
Flame/flow dynamics at the piston surface of an IC engine measured by high-speed PLIF and PTV
Carl-Philipp Ding, Brian Peterson, Marius Schmidt +2
Resolving fluid transport at engine surfaces is required to predict transient heat loss, which is becoming increasingly important for the development of high-efficiency internal co…
An application of tomographic PIV to investigate the spray-induced turbulence in a direct-injection engine
Harry Hill, Carl-Philipp Ding, Elias Baum +3
Fuel sprays produce high-velocity, jet-like flows that impart turbulence onto the ambient flow field. The spray-induced turbulence augments fuel-air mixing, which has a primary rol…
An experimental study of the detailed flame transport in a SI engine using simultaneous dual-plane OH-LIF and stereoscopic PIV
Brian Peterson, Elias Baum, Andreas Dreizler +1
Understanding the detailed flame transport in IC engines is important to predict ignition, rate of heat release and assess engine performance. This is particularly important for RA…
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…
