On Simulating Primary Atomization Using the Refined Level Set Grid Method
To simulate primary atomization, one has to track the position of the phase interface accurately, handle large numbers of topology changes and drops, treat the singular force of surface tension in an accurate and stable manner, and ensure grid-independent numerical results. To address all of these challenges we present a balanced force Refined Level Set Grid (RLSG) method for collocated, unstru...
متن کاملConservative Level Set/Ghost Fluid Method for Simulating Primary Atomization
This paper presents a novel approach for simulating incompressible two-phase flows by combining a conservative level set technique and the ghost-fluid method. Following the ideas of Olsson and Kreiss (2005), the liquid-gas interface is localized using a hyperbolic tangent level set that is transported and reinitialized using fully conservative numerical schemes. Mass conservation issues are gre...
متن کاملA Discontinuous Galerkin Conservative Level Set Scheme for Simulating Turbulent Primary Atomization
In an effort to improve the numerical schemes available for simulating of multiphase flows, a novel numerical method is developed to track the interface location. This method combines the excellent mass conservation properties of the accurate conservative level set (ACLS) method of Desjardins et al. [J. Comp. Physics 227 (18), 8395–8416] with a discontinuous Galerkin (DG) discretization. DG pro...
متن کاملDNS of Turbulent Primary Atomization Using a Level Set/Vortex Sheet Method
Modeling the primary atomization of turbulent liquid jets and sheets still remains an unsolved problem. Considering numerical grid resolutions typical for Large Eddy Simulations, the large scale liquid structures during primary breakup are well resolved, whereas all small scale structures are unresolved and thus require modeling. To help in the derivation of such subgrid models, DNS of the turb...
متن کاملAn accurate conservative level set/ghost fluid method for simulating turbulent atomization
This paper presents a novel methodology for simulating incompressible two-phase flows by combining an improved version of the conservative level set technique introduced in [E. Olsson, G. Kreiss, A conservative level set method for two phase flow, J. Comput. Phys. 210 (2005) 225–246] with a ghost fluid approach. By employing a hyperbolic tangent level set function that is transported and re-ini...
