Sustainably produced biofuels, especially when they are derived from lignocellulosic
biomass, are being discussed intensively for future ground transportation. Traditionally …

Optical imaging techniques are ubiquitous for the resolution of non-uniformities in gas flows.
Planar imaging techniques such as laser-induced fluorescence are well established and …

Optical diagnostics for fluid temperature measurements continue to further our
understanding of flows involving heat transfer and/or chemical reactions, which are intrinsic …

Sprays are among the most intellectually challenging and practically important topics in fluid
mechanics. This paper reviews needs, milestones, challenges, and a broad array of …

Combustion involves chemical reactions that are often highly exothermic. Combustion
systems utilize the energy of chemical compounds released during this reactive process for …

Ethanol-gasoline blended fuels have been widely applied in markets recently, as ethanol
reduces life-cycle greenhouse gas emissions and improves anti-knock performance …

Gaining information of species, temperature, and velocity distributions in turbulent
combustion and high-speed reactive flows is challenging, particularly for conducting …

Three-dimensional computed tomography of chemiluminescence (CTC) for combustion
diagnostics is attracting a surged research interest due to recent progress in sensor …

Abstract Laser-Induced Grating Spectroscopy (LIGS) is applied to premixed CH 4/air laminar
flat flames under operating pressures of 1 to 6 bar. For the first time, temperature and water …

For an improved understanding of the in-cylinder processes in internal combustion (IC)
engines, advanced diagnostics are needed to measure the thermodynamic state of the in …
