Research leading to these results has received funding from the Clean Sky 2 Joint Undertaking under European Union?s Horizon 2020 research and innovation programme through the ESTiMatE project, grant agreement 821418. We acknowledge PRACE for awarding us access to computational resources on JOLIOT CURIE-AMD at GENCI@CEA, France (proposal 2019204944). Support given to Carlos Moreno by Universitat Politecnica de Valencia through the ?FPI-Subprograma 2? grant within the ?Programa de Apoyo para la Investigacion y Desarrollo (PAID-01-19)? is acknowledged. We must thank Marco Crialesi and Wojciech Aniszewski for their technical advice on custom modifications on PARIS, and Johan Sundin for his implementation of the contact angle model. We also thank Achille Schmitter, Hugo Martinez and Lucas Gonzalez for help processing the 1-phase LES, 2-phase LES and DNS, respectively.
