The main aim of this project is to develop a ‘universal’ spray model applicable to a wide range of engineering and environmental applications, using the experience of the groups in St Petersburg and Brighton in developing models and their experimental validations for specific applications in fire suppression, liquefied gas depressurization and internal combustion engine research.
This project will be focused not just on collaboration between scientists in Russia and the UK, but also on the collaboration between the groups performing complementary research on sprays.
The new ‘universal’ spray model is expected to take into account the following characteristics of droplets and sprays:
The ETC model suitable for application to engineering computational fluid dynamics (CFD) codes was developed at the University of Brighton for applications in modelling Diesel engines. In this project the feasibility of using this model for simulation of fine water and Freon sprays, used for fire suppression, and liquefied gas depressurization sprays will be investigated.
In practically all known CFD codes the modelling of radiative heating of droplets is based on the assumption that droplets are opaque grey spheres. The model of radiative heating of droplets, developed at the University of Brighton, takes into account the effects of semi-transparency of droplets via a simple approximation of the results of Mie calculations. In this project the feasibility of using a similar model, for simulation of water and Freon sprays used for fire suppression and liquefied gas depressurization sprays will be investigated. In the cases of both ETC and radiative heating models, new applications of the model are expected to lead to further developments of the original applications.
The work on transient spray formation and droplet break-up is ongoing at the University of Brighton (as part of the EPSRC project Modelling of breakup processes in transient Diesel fuel sprays)
