Numerical simulation of the aerodynamic performance of an H-rotor

NUMERICAL SIMULA nON OF THE AERODYNAMIC PERFORMANCE OF AN H-ROTOR YanChen August 1 st, 2011 Vertical axis wind turbines (VAWTs) are devices to convert wind energy into electricity. Unlike horizontal axis wind turbines (HA WT) where the main rotor shaft is set horizontally, VAWTs use vertical rotor shaft. Unlike HAWTs, VAWTs can be effectively used in urban environment where flow is characterize...

Unstructured Mesh Generation including Directional Reenement for Aerodynamic Flow Simulation

A method for generating directionally reened unstructured tetrahedral meshes is presented. The motivation is the need to eeciently mesh the complex computational domains which are frequently encountered in aerospace applications. In this context, the method is applicable to the construction of meshes suitable for the simulation of inviscid and viscous aerodynamic ows. Minimum user intervention ...
