...Animesh Patari; Shantanu Pramanik; Tanmoy Mondal Purpose The present study scrutinizes the relative performance of various near-wall treatments coupled with two-equation RANS models to explore the turbulence transport mechanism in terms of the kinetic energy budget in a plane wall jet...

..., in a hierarchical, zonal fashion both the handling of turbulence and geometry is considered. Findings Such modelling of geometry is necessary to help deal with the increasingly coupled nature of many aerodynamic problems more economically and the drive towards considering ever increasing levels of geometrical...

... for the sake of comparison. The two decompositions are found practical in analysing the SDEs. The WCE is, in general, simpler, while WHE is more efficient as it is the limit of WCE when using infinite number of random variables. The Burgers turbulence is considered as a nonlinear example and WHE is shown...

...Zhitao Yan; Yongli Zhong; William E. Lin; Eric Savory; Yi You Purpose This paper examines various turbulence models for numerical simulation of a steady, two-dimensional (2-D) plane wall jet without co-flow using the commercial CFD software (ANSYS FLUENT 14.5). The purpose of this paper...

.... Originality/value – The paper offers two different approaches to solve turbulent swirling flows. One based in a general contrasted commercial tool and other using open source code. Both models show similar performance. An innovative set up for an axial swirler different from the conventional flat vanes...

... but the equation structure is similar to the time average k‐ε model. Ruprecht (2000) carried out static and dynamic interference calculations for the whole flow passage and obtained more comprehensive pulsation information. Chen (2000) employed a LES in simulating 3‐D turbulent flow through a pump...

...Marcela B. Goldschmit; Miguel A. Cavaliere The finite element solution of turbulent flows using a (k‐ε) turbulence model usually presents severe numerical difficulties. Develops an iterative (k‐L)‐predictor/ε‐corrector algorithm for overcoming this and solving the (k‐ε) turbulent models...

...Cheryl L. Sellers; Suresh Chandra For high speed shear layers, variable density extensions of standard incompressible turbulence models have not proved to be adequate in explaining the experimentally observed reduction in growth rate with increase in the convective Mach number. Recently, Sarkar...
