Multi-Phase Flows CFD Analysis
Multi-Phases flows involve combinations of solids, liquids and gases which interact. Computational Fluid Dynamics (CFD) is used to accurately predict the simultaneous interaction of more than one combination of phases that can be gases, solids or fluids. Typical applications involve sprays, solid particulate transport, boiling, cavitation, state-changes, free surface flows, dispersed multiphase flows, buoyancy problems and mixed species flows. For example, the risks from flow or process-induced vibration excitation of pipework are widely acknowledged in onshore process plants, offshore topsides and subsea facilities. Multiphase flow is particularly of concern because forces can vary considerably with flow regimes, and so relatively small changes in the gas to oil ratio can result in significant changes in dynamic force levels. These forces can be relatively broadband in nature and can therefore excite a range of structural modes.
Esimlab Engineering provides all forms of multi-phase flow analyses ranging from simple particle tracking calculations for industrial applications through to comprehensive design and optimisation of spray equipment and fluid jets. Esimlab engineering team quickly evaluate alternative product and process designs to increase efficiency, reliability, safety and durability in a competitive, time-critical environment.
