Experimental and numerical analysis of high pressure diesel spray–wall interaction
TL;DR: In this article, a mixed numerical-experimental approach is proposed to predict high pressure spray-wall interaction, especially under increasing back-pressures, and a modified version of the model is proposed and validated for low injection pressures (up to 300 bar) and ambient back-pressure.

Gasoline direct injection engines – A review of latest technologies and trends. Part 1: Spray breakup process
TL;DR: In this paper, a broad analysis of new mathematical models and experimental imaging techniques, used to study spray breakup and the subsequent impact on the engine surfaces, is reported and commented on, aiming at a broader understanding of the phenomena, a better characterisation of the jet, and the final optimization of the engine design.

Increasing energy efficiency of a gasoline direct injection engine through optimal synchronization of single or double injection strategies
TL;DR: In this paper, the results of numerical optimization analyses aimed at increasing the energetic efficiency of a GDI engine equipped with a high pressure multi-hole injector under both single and double injection events are reported.

Modeling Atomization of High-Pressure Diesel Sprays
TL;DR: In this article, the authors deal with a numerical and experimental characterization of a high-pressure diesel spray injected by a common-rail injection system and they use both the TAB model and a hybrid model that allows one to describe both liquid jet atomization and droplet breakup.

CFD optimization for GDI spray model tuning and enhancement of engine performance
TL;DR: CFD based optimization (CFD-O) is carried out on a single cylinder, fourvalve, four-stroke gasoline direct injection (GDI) engine, to enhance mixture formation under stratified charge operation, hence to choose between the single or double injection strategy maximizing the engine power output.
