2D numerical investigation of liquid dispersion in rotating packed bed and its comparison with experimental measurements using high-speed camera [PDF]

open access: yesEPJ Web of Conferences, 2022
Study deals with liquid dispersion of water in unstructured wire mesh of rotating packed bed, experimentally investigated using high speed camera. Dispersed water in outer region of rotating packed bed were captured by high-speed camera and droplet size ...

Application of Different Turbulence Models Simulating Wind Flow in Complex Terrain: A Case Study for the WindForS Test Site

open access: yesComputation, 2018
A model for the simulation of wind flow in complex terrain is presented based on the Reynolds averaged Navier–Stokes (RANS) equations. For the description of turbulence, the standard k-ε, the renormalization group (RNG) k-ε, and a ...

INFLUENCE OF DIFFERENT WIND ANGLES ON PEDESTRIAN WIND COMFORT IN 3D SPACE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Wind can impact pedestrian comfort. This comfort can be observed by integrating a 3D city model into the study area. However, little research has been done on the influence of different wind angles on pedestrian wind comfort and rarely on implementing 3D

Fluid Flow Simulations of a Vane Separator [PDF]

open access: yesModeling, Identification and Control, 2002
In this work, the fluid flow in a vane separator is simulated by Computational Fluid Dynamics (CFD). Detailed measurements of air flow inside a single passage in a vane separator have earlier been presented (Josang and Melaaen 2000).

Ram pressure stripping of the hot gaseous haloes of galaxies using the k-epsilon sub-grid turbulence model [PDF]

open access: yes, 2013
We perform three dimensional hydrodynamic simulations of the ram pressure stripping of the hot extended gaseous halo of a massive galaxy using the k-epsilon sub-grid turbulence model at Mach numbers 0.9, 1.1 and 1.9. The k-epsilon model is used to simulate high Reynolds number flows by increasing the transport coefficients in regions of high turbulence.

CFD-Modeling of the Airfoil of the Blades of a Wind Power Plant with a Vertical Axis in the Ansys Fluent System

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика
The article presents the results of research on modeling the DU-06-W-200 airfoil used in wind power plants with a vertical axis in the Ansys Fluent system, evaluating compatibility with experimental data and determining the optimal angle of attack.

CFD Wake Modelling with a BEM Wind Turbine Sub-Model [PDF]

open access: yesModeling, Identification and Control, 2013
Modelling of wind farms using computational fluid dynamics (CFD) resolving the flow field around each wind turbine's blades on a moving computational grid is still too costly and time consuming in terms of computational capacity and effort.

Computation of supersonic jet mixing noise for an axisymmetric CD nozzle using k-epsilon turbulence model

open access: yes, 1992
The turbulent mixing noise of a supersonic jet is calculated for a round convergent-divergent nozzle at the design pressure ratio. Aerodynamic computations are performed using the PARC code with a k-epsilon turbulence model.
