Analysis of fuel film formation process at low temperature by wall impingement direct injection gasoline spray

Nihon Kikai Gakkai ronbunshu, 2022
In a direct-injection gasoline engine, strict control of pollutant emissions at cold start is a critical point to comply with new regulations, and the fuel film formed by spray impingement on the piston wall is closely related.

Cold Gas Dynamic Spray (CGDS) Technology and Applications

Academic Platform Journal of Engineering and Science, 2013
Thermal spray coatings are obtained by sending powder particles with high heat and/or kinetic energy onto a target substrate material in molten or semi-molten form. Nowadays, thermal spray coatings are used in many areas such as particularly aviation and defense industry and also energy, electronic and biomedical applications.

Condensable Particulate Matter Removal and Its Mechanism by Phase Change Technology During Wet Desulfurization Process

Separations
Limestone-gypsum wet flue gas desulfurization (WFGD) played a key role in SOx removal and clean emissions. However, it would also affect the condensable particulate matter (CPM) removal and compositions.

Simulation of gas-substrate heat exchange during cold-gas dynamic spraying

International Journal of Thermal Sciences, 2012
Abstract In this study, the Nusselt numbers of impinging compressible fluid jets originating from a cold-gas dynamic spraying nozzle were determined. A low-pressure cold-gas dynamic spraying unit was used to generate a jet of hot compressed nitrogen that impinged upon flat substrates.

Experimental and simulation study on evaporation characteristics of E85 impinging spray under DISI cold-start condition

Applications in Energy and Combustion Science, 2023
The direct injection of ethanol-gasoline blended fuel into the engine cylinder near the top dead center (TDC) is evitable to suffer from the wall impingement due to more injection mass required to maintain the same air/fuel ratio with traditional fossil ...
