A Comprehensive Study on Numerical and Computational Aspects of Turbulence Modelling

Abstract

Computational fluid dynamics (CFD) is the analysis of the system involving fluid flow, heat transfer and transport phenomena such as chemical reaction, combustion by means of computer based simulation. In the present work, the numerical models, governing equations involved in CFD, Reynolds Averaged Navier-Stokes equation along with the k-epsilon model for modelling of turbulence has been studied numerically and computationally to analyze a fluid flow in Y-duct using ANSYS FLUENT 16.2 as a solver. The flow was analyzed and flow characteristics for output were identified by the CFD solver.
