Vapor Cycle System - Heat Exchanger performance 3D modeling with different new low GWP refrigerants

The objective of this topic is to gain knowledge on physics involved inside two-phase heat exchangers and more explicitly in evaporators, and in particular to understand the impact on performance and pressure drop of the following parameters: gravity field, titer quantity and spacial distribution, mass flow rate of refrigerant, HX structure. Hence a multi-scale modeling approach is awaited in order to focus on various physical phenomenon induced in the heat exchanger. This numerical approach shall be validated by experimental developments led under a design of experiments. Please refer to the full topic descriptions document published in this call.
