Abstract: This paper presents the dynamic investigation of an existing wind turbine tower. Both experimental and numerical analyses were performed to assess the structural response of the tower under seismic load. Field ambient vibration test was applied to identify the actual dynamic properties experimentally. A vibration based finite element model was built in ANSYS to conduct the seismic response analysis. The tower shown to survive moderate earthquakes as it is located in Zafarana wind farm in Egypt, a zone lies by the red sea known for its historical seismic activity.

Abstract: The combustion of sodium droplet is simulated numerically. The flow fields in and around the droplet are obtained by solving the Navier-Stokes equations and the energy conservation equations. The reaction rate for the pre-ignition stage combustion is modeled using a kinetics based model, while that for the vapor phase after ignition is based on the mass transfer rate of oxygen. The droplet motion with temperature variation is shown, and compared with the existing experimental data, Reasonable agreement is shown between the simulated and the experimental results.
