Abstract
Abstract The present paper summarises detailed experimental and numerical studies on stationary turbulent sprays performed by the authors research group over the past 5 years. The main objective of these studies was related to the improvement and validation of the Euler/Lagrange approach for the numerical prediction of spraying systems. For this purpose three different spray configurations were considered, a hollow cone spray issuing into a low speed air stream, a spray interacting with a solid cone, and a hollow cone spray being injected into a heated air stream. The first case focuses on the effect of droplet collisions and coalescence and evaporation, the second case concentrates on the modelling of secondary atomisation associated with a spray-wall interaction and the third case is related to spray evaporation in a moderately heated turbulent air stream. For all these cases detailed measurements by phase-Doppler anemometry were performed in order to provide appropriate inlet conditions and data for the validation of the predictions.
