Comparison of the results of applying the turbulence model VT−92 and two-fluid model to the problem of a subsonic axisymmetric jet [PDF]

open access: yesE3S Web of Conferences, 2023
This article studies an axisymmetric subsonic jet based on modern turbulence models. This task, despite its simplicity, is a rather complex problem for modeling turbulence.

The Transport and Evolution of MHD Turbulence throughout the Heliosphere: Models and Observations

open access: yes, 2021
A detailed study of solar wind turbulence throughout the heliosphere in both the upwind and downwind directions is presented. We use an incompressible magnetohydrodynamic (MHD) turbulence model that includes the effects of electrons, the separation of ...

Toy models of developed turbulence

open access: yesCondensed Matter Physics, 2005
We have investigated the advection of a passive scalar quantity by incompressible helical turbulent flow within the framework of extended Kraichnan model. Turbulent fluctuations of velocity field are assumed to have the Gaussian statistics with zero mean

Numerical Study of the Effect of Freestream Turbulence on by-pass Transition in a Boundary Layer [PDF]

open access: yes, 2014
We use direct numerical simulations in the presence of free-stream turbulence having different values of intensity, T u, and integral length scale, L, in order to determine which kind of structures are involved in the path to transition of a boundary ...

Teaching turbulent flow through pipe fittings using computational fluid dynamics approach

open access: yesEngineering Reports, 2020
The largest network of fluid transportation in the world is through pipelines. During the transportation of fluids through pipes, several “fittings” are used in the piping system such as elbows, T‐junctions, reducers, expanders, bends, couplings, valves,

Developments in turbulence research: a review based on the 1999 Programme of the Isaac Newton Institute, Cambridge [PDF]

open access: yes, 2001
Recent research is making progress in framing more precisely the basic dynamical and statistical questions about turbulence and in answering them.

Numerical Simulation Strategy Optimization Analysis of Submarine Resistance and Flow Field

open access: yesShanghai Jiaotong Daxue xuebao, 2022
In order to explore the influence of different turbulence models on the resistance and flow field of an advancing submarine, based on the STAR-CCM+platform, and taking Sub-off as the geometric model, this paper adopts the finite volume method, combing 10

Nested polyhedra model of turbulence [PDF]

open access: yesPhysical Review E, 2017
A discretization of the wave-number space is proposed, using nested polyhedra, in the form of alternating dodecahedra and icosahedra that are self-similarly scaled. This particular choice allows the possibility of forming triangles using only discretized wave-vectors when the scaling between two consecutive dodecahedra is equal to the golden ratio, and
