an investigation of reynolds number effect on the aerodynamics of bluff body with sharp edges

in general, the aerodynamic stability of long span bridges is evaluated based on the results of wind tunnel tests in the low reynolds number region, because in almost all wind tunnel tests, it is impracticable to satisfy reynolds number similitude. therefore, in order to correctly evaluate conventional wind tunnel test results, reynolds number effects on the aerodynamic force coefficients acting o...

Numerical and Experimental Investigation of Helicopter Fuselage Aerodynamics

The aerodynamic characteristics of an isolated MRH 90 helicopter fuselage have been investigated using Computational Fluid Dynamics (CFD). Simulations utilised an unstructured tetrahedral grid and both the k-ε and k-ω SST turbulence models were investigated. Standard ‘law of the wall’ wall functions were incorporated, along with a segregated finite volume solver. A wind tunnel testing program w...

Numerical Simulation of Two- Dimensional Complex Flows around Bluff Bodies Using the Immersed Boundary Method

This paper presents a two-dimensional numerical simulation of flows around different bluff bodies, at Re = 100 and 200, using the Immersed Boundary (IB) method, as a sequence of a previous work. The force density term required by the IB method is obtained with the Virtual Physical Model (VPM). Simulations were carried out for two circular cylinders of different diameter in tandem, two cylinders...

Towards Wavelet-based Adaptive Numerical Simulation of Turbulent Flow past Bluff Bodies

By combining a wavelet-based grid adaptation strategy with the Brinkman penalization technique an efficient numerical method to simulate turbulent flow past bluff bodies is obtained. The approach is very promising for the simulation of turbulent flows of scientific and engineering interest. To demonstrate the feasibility of the method some preliminary numerical experiments are conducted for flo...

Turbulence intensity effect on the bluff bodies aerodynamic behavior

Slender high rise structures are exposed to aerodynamic problems connected to the windstructure interaction, for example vortex shedding or dynamic instability (e.g. galloping). Generally the design of these structures requires the aid of wind tunnel tests on scaled models. The paper investigates the aerodynamic behavior of a bluff body and the shape is adopted for section of the tower of a cab...
