The present study explores the validity of the available modelling techniques for the study of two-phase flow standing waves between incompressible immiscible fluids, specifically air and water, using OpenFOAM™. In previous projects, consultancy firms have had troubles resolving hydraulic jumps using OpenFOAM™.  To that end, numerical simulation campaigns will be conducted and validated against experimental studies on hydraulic jumps made by WL. The present project will:

• Assess the available CFD tools within KUSTWATCON (namely OpenFOAM™), for the simulation of two-phase flows of interest in Environmental Engineering, using available EFD data. Such an assessment involves the evaluation of different numerical schemes, and turbulence models.
• Study the different physical mechanisms present in a hydraulic jump, by using the available EFD data and the numerical results obtained.
• Propose improvements for the current modelling issues present.
