These investigations aim to validate the applicability of a concept for fuel-air-ratio measurements by laser-induced fluorescence (FARLIF) at elevated temperatures. For the commonly used model fuel isooctane with the fluorescence tracer toluene the FARLIF applicability was confirmed with an excitation wavelength of 266 nm for fuel-air mixtures with λ ≥ 0.2(More)
Laser induced fluorescence is used to develop a 2D measurement technique for mixture formation analysis of fuel and air in a broad temperature regime from 398 K up to 548 K. The measurement principle is called FARLIF (fuel-air ratio by laser-induced fluorescence). Its application is tested on the tracer toluene in the non-fluorescent model fuel isooctane as(More)
The authors developed and qualified an automated routine screening tool to quantify hair shine. This tool is able to separately record individual properties of hair shine such as specular reflection and multiple reflection, as well as additional features such as sparkle, parallelism of hair fibers, and hair color, which strongly affect the subjective(More)
