Abstract:
|
A level-set model is proposed for simulating interfacial heat or mass transfer in two-phase flows. The Navier-Stokes equations as well as the heat transfer or mass transfer equations are discretized using a finite-volume approach on a collocated unstructured mesh, whereas a multiple marker level-set methodology is introduced in order to avoid the numerical coalescence of the fluid interfaces. Some numerical examples are considered to show the capabilities of this model, including pure diffusion of a chemical species with chemical reaction, and buoyancy-driven motion of bubble swarms with mass transfer. Present results are compared against analytical and empirical correlations from the literature as validations of the proposed model. |
