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…
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…
