Etude de la fragmentation d'une goutte de métal liquide dans l'eau

Abstract : The study presented in this report concerns theoretical and experimental modelisation of secondary atomization process. In the analytic part, a new model of fragmentation of droplets has been developed and studied. This model has shown a good accuracy compared to experimental results, especially at low Weber numbers. Though, further modifications are expected to improve modeling at a wide range of Weber and Ohnesorge numbers. In the experimental part, a molten metal drop-on-demand generator has been successfully designed and manufactured. This generator is characterized by its ability to produce large droplets (diameter up to 1 centimeter). Studying the physical properties of Field metal was essential to finish the previous design. This metal has shown a complex rheological behavior. After many experiments using glycerin and Field metal, the droplet generator has proven a good reproducibility regarding the number of the droplets produced and their size.
