A direction splitting scheme for Navier-Stokes-Boussinesq system in spherical shell geometries Int. J. Numer. Methods Fluids (IF 2.107) Pub Date : 2021-09-15 Aziz Takhirovb, Roman Frolovc, Peter Mineva
This paper introduces a second-order direction-splitting method for solving the incompressible Navier-Stokes-Boussinesq system in a spherical shell region. The equations are solved on overset Yin-Yang grids, combined with spherical coordinate transforms. This approach allows to avoid the singularities at the poles and keeps the grid size relatively uniform. The downside is that the spherical shell

Numerical prediction of breakup mode of contracting gas filament in liquid Int. J. Numer. Methods Fluids (IF 2.107) Pub Date : 2021-09-12 Yang Ma, Yongpan Cheng, Dongjie Zhang, Ke Zhang, Fan Wang
The breaking up of gas filament in liquid is important in many industrial and scientific applications. In this study a transient axisymmetric model with the level set method is built up to examine the dynamics of a contracting gas filament, and to determine the effects of the aspect ratio, Ohnesorge (Oh) number, and viscosity ratio on its breakup mode. The filament undergoes no break, middle break

An Efficient Edge Based Data Structure for the Compressible RANS Equations on Hybrid Unstructured Meshes Int. J. Numer. Methods Fluids (IF 2.107) Pub Date : 2021-09-09 Semih Akkurt, Mehmet Sahin
An efficient edge based data structure has been developed in order to implement an unstructured vertex based finite volume algorithm for the Reynolds-averaged Navier-Stokes (RANS) equations on hybrid meshes. In the present approach, the data structure is tailored to meet the requirements of the vertex based algorithm by considering data access patterns and cache efficiency. The required data are packed
