A generalised Fully Lagrangian Approach for gas-droplet flows

Project Details


This project synthesises mathematical and engineering approaches to the simulation of gas-droplet flows, and includes the development of a novel mathematical formalism.

The project focuses on non-trivial generalisation of the version of the Fully Lagrangian Approach (FLA) developed by Osiptsov, also known as the Osiptsov method.

This method is recognised as a promising approach to calculating particle/droplet concentrations. However, its current applications are restricted to specific types of flow within a dilute mono-sized admixture. The novel model to be developed in the framework of the project will take into account droplet evaporation, polydispersity of an admixture, and the effect of droplets on the carrier phase (two-way coupling).

The corresponding mathematical model will be formulated and implemented in the Computational Fluid Dynamics (CFD) software OpenFOAM, an open-source and widely used CFD software, which will make the project outcomes accessible to specialists interested in sprays.

The developed model will be applied to simulate the evolution of droplet distribution in sprays formed by a gasoline or diesel injector. The results of the numerical simulations will be validated against experimental data collected in the Advanced Engineering Centre (AEC), at the University of Brighton (UoB).
