Spray combustion is encountered in many engineering applications, such as internal combustion engines and gas-turbine aircraft engines. In these systems, the concurrent processes of liquid atomization, droplet evaporation, turbulent dispersion, and combustion interact and strongly affect each other, which makes experimental measurement and high-fidelity simulation challenging. To understand the...

The use of vibration signals for internal combustion engines diagnosis is now well established for several applications such as knock detection or valve mechanics behaviour assessment. If standard knock detection can be performed in real time, diagnoses are generally carried out off-line due to algorithm complexity. Our aim was to get some insights on the time-frequency properties of the vibrat...

Flame ignition or extinction is the result of very complex interactions between combustion chemistry and turbulence. It has been recently observed in experimental studies [1,2] that the presence of a plasma discharge in the vicinity of reaction zones affects combustion. For instance, a discharge generated in a combustion chamber produces a pool of radicals. These highly reactive species strongl...

Abstract In an experimental procedure, a voltage rise anemometry is developed as measurement technique for turbulent flows. Initially, fundamental investigations on specific wind tunnel were performed basic understanding and calibration purpose. Thus, mathematical correlation derived calculating flow from measured secondary of ignition system under different thermodynamic conditions. Subsequent...

The reduction in environment pollutant emissions is one of the main challenges regarding ground transportation. Internal combustion engines, used especially hybrid propulsion systems, may be a solution transition to fully electric cars. Therefore, more efficient engines terms fuel consumption, emission generation and power density must developed. This paper presents research architecture chambe...
