چکیده
We present a novel interface-capturing scheme, THINC-scaling, to unify the VOF (volume of fluid) and level set methods, which have been developed as two different approaches widely used in various applications. The key success is maintain high-quality THINC reconstruction function using field accurately retrieve geometrical information fulfill numerical conservativeness. interface well defined surface form high-order polynomial, so-called polynomial (PSI). then update via finite volume method, semi-Lagrangian method. Seeing aspects function, THINC-scaling scheme preserves at same time advantages both i.e. mass/volume conservation method faithfulness through straightforward solution procedure. allows represent an with polynomials has algorithmic simplicity largely eases its implementation unstructured grids. Two three dimensional algorithms structured grids verified. results reveal that capturing able provide high-fidelity comparable other most advanced more profoundly it can resolve sub-grid filament structures if represented by higher than second order.

A Constrained Level Set Method for Simulating the Formation of Liquid Bridges
Abstract. In this paper, we investigate the dynamic process of liquid bridge formation between two parallel hydrophobic plates with hydrophilic patches, previously studied in [1]. We propose a dynamic Hele-Shaw model to take advantage of the small aspect ratio between the gap width and the plate size. A constrained level set method is applied to solve the model equations numerically, where a gl...
متن کاملA BINARY LEVEL SET METHOD FOR STRUCTURAL TOPOLOGY OPTIMIZATION
This paper proposes an effective algorithm based on the level set method (LSM) to solve shape and topology optimization problems. Since the conventional LSM has several limitations, a binary level set method (BLSM) is used instead. In the BLSM, the level set function can only take 1 and -1 values at convergence. Thus, it is related to phase-field methods. We don’t need to solve the Hamilton-Jac...
متن کاملLevel Density in the Complex Scaling Method
It is shown that the continuum level density (CLD) at unbound energies can be calculated with the complex scaling method (CSM), in which the energy spectra of bound states, resonances and continuum states are obtained in terms of L basis functions. In this method, the extended completeness relation is applied to the calculation of the Green functions, and the continuum-state part is approximate...
