Research Project
Multiscale two-phase gas-liquid flows are commonly found in numerous chemical engineering applications such as bubble columns. Therefore, understanding the hydrodynamic behaviour of such systems is essential in the design, operation and control of these processes. Since experimentation is time-consuming, costly and unable to provide information about the continuously varying spatial fields, Computational Fluid Dynamic (CFD) is a desirable approach to study these multiscale systems. Among the available CFD modelling approaches, two-fluid model is an attractive option since it is less computationally intensive compared to Euler-Lagrange and interface-tracking (e.g. phase-field) methods. Although two-fluid model results in accurate solutions for dispersed bubble regimes, this method cannot capture the effect of different interface sizes in the systems with multiscale interfaces including the systems in which dispersed and segregated phases coexist.
My research aims to develop a hybrid two-fluid/phase-field method that can be used to model multiscale gas-liquid systems. The phase-field model will be applied in segregated phase sub-domains to maintain the accurate resolution of large interfaces while the two-fluid model will be used in sub-regions that include dispersed phase to reduce the computation complexity.
Currently, I am working on developing an accurate formulation for the hybrid two-phase/phase-field model.
