A three dimensional non-hydrostatic model for turbulent air flow
Vietnam Journal of Mechanics, 2000 A finite-volume code is developed to compute the turbulent airflow over small- scale complex terrain. A pressure-correction algorithm is used to solve the three-dimensional non-hydrostatic flow equations. The turbulent transport is simulated by the k- €

Three-dimensional extensions to Jeffery–Hamel flow [PDF]
Fluid Dynamics Research, 2001 Summary: We consider two viscous flows, both of which are in a class of three-dimensional flow states that are closely related to the classical Jeffery-Hamel solutions. In the first configuration, we consider a flow between two planes, intersecting at an angle \(\alpha\), and driven by a line-source-like solution in the neighbourhood of the apex of ...

Modification of three-dimensional transition in the wake of a rotationally oscillating cylinder [PDF]
, 2010 A study of the flow past an oscillatory rotating cylinder has been conducted, where the frequency of oscillation has been matched to the natural frequency of the vortex street generated in the wake of a stationary cylinder, at Reynolds number 300.

THREE DIMENSIONAL FLOW STRUCTURES AROUND A DEEP SCOUR HOLE
E3S Web of Conferences, 2018 The existence of a planform vortex is considered to be the cause of development and sustention of large-scale local scouring in the Kiso River. In order to make clear the 3D flow structures in this deep local scour, we conducted a field observation and ...

Experimental Study on a Three-Dimensional Wall Jet
Journal of Fluid Science and Technology, 2007 This study is to clarify the flow structure of a three-dimensional wall jet discharged tangentially on a flat surface from a circular nozzle. Distributions of the mean velocities and fluctuating velocities in a cross section of a fully-developed flow ...

Robust construction of the three-dimensional flow complex [PDF]
Proceedings of the twenty-fourth annual symposium on Computational geometry, 2008 The Delaunay triangulation and its dual the Voronoi diagram are ubiquitous geometric complexes. From a topological standpoint, the connection has recently been made between these cell complexes and the Morse theory of distance functions. In particular, in the generic setting, algorithms have been proposed to compute the flow complex - the stable and ...

Traveling wave solutions for (3 + 1) dimensional equations arising in fluid mechanics
Nonlinear Engineering, 2014 In this note, traveling wave solutions for (3 + 1) dimensional fluid models of incompressible flow are considered. The governing partial differential equations of two models are reduced to ordinary differential equation by employing wave ...
