Ice formation at lifting surfaces and engine intakes is a significant issue affecting regular aircraft operation. The icing on a wing's leading edge perturbs the airflow around the wing, contributing to a decrease in lift and increasing drag. A step towards the understanding of droplet dynamics under cryogenics is made in the present work. An in-ho...

The crystallization of water droplets is a ubiquitous phenomenon, which plays a fundamental role in many natural and artificial processes. This phenomenon gained particular interest in the aeronautical industry due to ice accretion on lifting surfaces and engine intakes. A performance study is made of several models for predicting cooling and freez...

This work enhances the understanding of droplet dynamics under cryogenics conditions through an in-house developed analytical tool used to predict the supercooling of water droplets. The physical process is based on a full-scale four-stage supercooling process in which the recalescence stage is assumed instantaneous and the crystallization kinemati...

The present paper describes a tool developed in-house for the modeling of free-falling water droplet cooling processes. A two-way coupling model is employed to account for the interactions between the droplets and the carrier fluid, following a Eulerian-Lagrangian approach. In addition, a stochastic separated flow technique is employed, involving r...
