What is it about?
Liquid jet modeling impinging on a flat surface, is part of a research program to design a test bench for aircraft deicing. Testing will simulate various scenarios of ethylene glycol spraying on the cold surface mock-up of an aircraft wing. The spray characteristics, such as the projection angle, pressure, temperature, distance between the spray exit and the impact point, will be controlled during simulation. These parameters will allow the measurement of ground deicing quality levels. In the long term, after ruling on the formula with the best performance, this study will be used to improve ground deicing personnel training and to reduce pollution.

Why is it important?
Numerical simulations will improve propylene glycol application by identifying critical parameters such as liquid film thickness. Some considerations were made on the environmental impact that the use of glycol and natural gas would have on the future of deicing techniques, and how these new techniques would change the current system and its procedures.
