Windy Cities

Modelling and Validation of Wind Evolution in an Urban environment


Wind evolution, the process of how the turbulence eddies are evolving during travelling with the main stream, is usually described with longitudinal coherence model mathematically. The motivations to model the wind evolution are to get a better understanding of turbulence structure and to provide important information for design of lidar-assisted wind turbine control. This PhD project aims to deduce a parameterization model for the longitudinal coherence model using measurement data. The parameterization model is expected to be able to adjust the coherence model according to different wind conditions and environmental affects. Besides that, it is also expected to propose a general work flow for measurement-based model deduction. This PhD project is a part of the Graduate School WindyCities.
