Sensors are perhaps the most important and integral components of our modern society.
With global warming and environmental pollution garnering ever-increasing attention, as …

Multi-cycle direct numerical simulations (DNS) of a laboratory-scale engine at technically
relevant engine speeds (1500 and 2500 rpm) are performed to investigate the transient …

We demonstrate a hybrid time–frequency spectroscopic method for simultaneous
temperature/pressure measurements in nonreacting compressible flows with known gas …

Due to the influence of chemical reactions, phase change, and other phenomena, the
combustion system is a complicated high-temperature environment. Therefore, the spatio …

Coherent Raman scattering (CRS) spectroscopy holds versatile applications in many fields
ranging from measuring temperature and concentration in reacting flows to imaging …

Laser diagnostic techniques have for more than five decades been used for gaining a
deepened understanding of various combustion processes. The main reason for this is the …

Abstract Design of efficient, downsized piston engines requires a thorough understanding of
transient near-wall heat losses. Measurements of the spatially and temporally evolving …

A discrete tomographic imaging method is introduced to reconstruct distributions of
temperature and gas molar concentration in tunable diode laser absorption spectroscopy …

We present a multi-focus fs/ps-CARS scheme to perform spectroscopy on multiple points
simultaneously for gas phase measurements and microscopy, using a single birefringence …

Optical diagnostics of gas-phase pressure are relatively unusual. In this work, we
demonstrate a novel, rapid, and robust method to use laser-induced grating scattering …
