Wind Features and Wind Velocities [PDF]
Fast winds have been detected in the spectra of many nuclei of planetary nebulae (PNNi). The wind velocities range from about 600 km/s to roughly 4000 km/s. While these winds add little to the mass of the nebular shells they may significantly effect their internal kinematics.By studying the emission from the faint outer envelopes of PNe one can infer ...

The effect of inlet curvature and flange on wind turbine diffuser performance
The modification is required to the conventional wind turbine in order to increase the power produced by the wind turbine located in the low wind velocity area. Attaching a diffuser to the conventional wind turbine is one of the ways to increase the wind

Characteristics of Wind Velocity and Temperature Change Near an Escarpment-Shaped Road Embankment
Artificial structures such as embankments built during the construction of highways influence the surrounding airflow. Various types of damage can occur due to changes in the wind velocity and temperature around highway embankments.

Performance Comparison of Different Building Shapes Using a Wind Tunnel and a Computational Model
A building-integrated wind turbine (BIWT) is an alternative way to assess renewable energy. BIWTs produces their own energy without relying on fossil fuels. However, only a few researchers have studied BIWTs.
