On the Influence of Droplets Non Sphericity on their First Rainbow Pattern and our Capability to Correctly Estimate their Size and Temperature

Kuan Fang Ren

Résumé

The influence of droplets non sphericity on their rainbow scattering diagrams is investigated with a vectorial complex ray model and experiments carried under acoustic levitation. It is shown that quasi-imperceptible change in the morphology of large droplets can significantly affect the structure of their scattering pattern and hence any estimation of their size and temperature-unless a proper a particle shape and light scattering models are used.
