Research on Measurement and Simulation of the Wind Environ- Ment around Buildings in Campus
The wind environment around a building influences human lives and the design of it. Simulation by CFD software is a main method used to study wind environment. But the reliability of the simulation result needs to be proved by comparing to the measured wind environment data. Experiment and simulation on wind environment were carried out in this reasearch. What’s more, different simulation metho...
متن کاملValidation Process for CFD Simulations of Wind Around Buildings
Our study is based on a great number of CFD (computational fluid dynamics) simulations to evaluate wind comfort at the pedestrian level. This article explains the method used to validate our CFD simulations carried out with the FLUENT software. This validation is based on a comparison between our simulated results and wind tunnel tests for three different building contexts: a single building, t...
متن کاملSpeed Control of Wind Turbine through Pitch Control Using Different Control Techniques
Pitch control is one of t he major aspects of wind turbine control, particularly over high wi nd s p e e d a n d oscillations. General El e c t r i c (GE) model of wi n d t ur bi ne i s practically compatible with the structure of the wind turbines. I t h a s b e e n p r o v e d t h a t simulation results using this model are closer to the actual case, compared to other available mod...
متن کاملImproving System Identification using Clustering
System identification involves identification of a behavioral model that best explains the measured behavior of a structure. This research uses a strategy of generation and iterative filtering of multiple candidate models for system identification. The task of model filtering is supported by measurement cycles. During each measurement cycle, the location for subsequent measurement can be chosen...
متن کاملAdvanced System Identification Techniques for Wind Turbine Structures
The new approach to modal parameter identification, presented in this paper, uses an asymptotically stable observer to form a discrete state-space model for a wind turbine structure. The identification is per formed using input-output time-series. A special software package developed in this research has been tested using the data generated by the ADAMS�1 model of the Micon 65/13 wind turbine ...
