Aerodynamic forces on iced cylinder for dry ice accretion – A numerical study

Numerical Simulation on the Aerodynamic Force of the Iced Conductor for Different Angles of Attack

Article history: Received: 19.06.2014. Received in revised form: 06.11.2014. Accepted: 11.11.2014. According to the galloping mechanism of iced conductors, the aerodynamic simulations were performed based on actual wind tunnel tests. Aeroelastic models of single and bundled conductors with a typical ice-coating section forms (crescent section) were set up. The simulation results were in good ag...

Wind tunnel effects on ice accretion over aircraft wings

Reference ice accretion experiments are reproduced numerically using the simulation framework PoliMIce to investigate solid blockage effects and wall-model boundary layer interaction at the wall-model juncture. The open-source OpenFOAM software is applied to the computation of the aerodynamic flow-field and of the trajectories of water droplets. The thickness of the iced layer is then determine...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

A Numerical Study on the Aeroacoustic Radiation from a Finite Length Rotating Cylinder

Rotating cylinders have wide applications in different areas, especially the aerodynamic area. However, the acoustic behaviors of these components have not been widely studied. The generating noise from a spinning cylinder is mainly due to the detached vortices from the leeward of the body. In this study, the large eddy simulation technique is used to simulate the flow field over a three-dimens...
