The spectral emissivity of an object is required to measure its temperature remotely, based
on thermal imaging from a high-speed digital camera. However, it is often difficult to obtain …

In this work, a multi-wavelength pyrometry method is proposed in order to evaluate soot
temperature for laminar axisymmetric non-premixed flames. A single radiative model that …

Optical and intrusive measurement techniques for temperature and soot concentration in hot
reacting flows were tested on a small-scale burner in fuel-rich, oxygen-enriched atmospheric …

Firebrands can dramatically increase the hazards of wildland fires. While embers have been
extensively studied, little is known about their temperatures. To address this an imaging …

The simultaneous reduction of fuel consumption and pollutant emissions such as Nitrogen
oxides (NO x) and soot remains the primary goal of modern engine development. In this …

The use of fuels made from renewable resources can be beneficial in reducing the CO 2
emission balance of the existing vehicle fleet. These fuels should be drop-in-capable, ie …

The soot emissions from internal combustion engines have significant health and
environmental impacts and, as such, are subject to increasingly stringent regulations. Two …

To achieve precise temperature measurement of two-dimensional high-temperature flow
fields, a data processing method for two-color pyrometers was designed based on the …

This work assesses the soot formation and oxidation processes in a high-pressure direct
injection natural gas engine using simultaneous high-speed two-colour pyrometry and OH …

A low level of pollutant emissions was reached because of stepwise tightened emission
legislation, while it was possible to keep or to improve further the efficiency of the drive train …
