Simulation of Wake Effects Applying CFD Technique to the K-Ε Model

Abstract

Carlos Armenta-Deu, Raul Fernandez and Jorge Contreras

In this work, we develop a simulation study on the wake effects in turbulent fluid regimes using CFD techniques to the k-ε model. We apply the k-ε model to solve the Navier-Stokes equations, capturing the most relevant parameters affecting the performance of the turbulent fluid when wake effects occur. The study focuses on the kinetic energy and energy dissipation rate, modeling the wake-time evolution to obtain its spatial distribution. The modeling and simulation produce a detailed wake velocity profile, which is critical in determining the wake impact on downstream elements. The simulation results evaluation applies to improve the design of energy use downstream systems by minimizing energy losses and improving efficiency. The study applies to rotating obstacles but is valid for other fluid applications.
