چکیده

A Neutron Transport Code ATES3 (Anisotropic Transport Equation Solver in 3D), which was developed at BARC for the deterministic solution of 3D steady-state neutron transport problems, has been parallelized using Message Passing Parallel Programming model on BARC’s ANUPAM Parallel Supercomputer. The most time consuming step in the code ATES3, which is transport sweep, was made parallel using three different data-decomposition techniques, namely, parallelization in angular variable, parallelization using Diagonal Sweep approach and in the third approach, optimization techniques are being applied in Diagonal Sweeping. In the paper, we discuss the problem domain, parallelization techniques used and present the performance figures obtained with each approach.

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver

In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...

A Message-Passing Distributed Memory Parallel Algorithm for a Dual-Code Thin Layer, Parabolized Navier-Stokes Solver

In this study, the results of parallelization of a 3-D dual code (Thin Layer, Parabolized Navier-Stokes solver) for solving supersonic turbulent flow around body and wing-body combinations are presented. As a serial code, TLNS solver is very time consuming and takes a large part of memory due to the iterative and lengthy computations. Also for complicated geometries, an exceeding number of grid...
