Abstract
THESIS SUMMARY
The current study experimentally and numerically investigates the effect of the wake interaction among multi turbines of straight bladed Darrieus vertical axis wind turbines. The experimental study was conducted using a wind tunnel with an open test section. The uniformity of the wind tunnel was studied and enhanced to give a better face velocity distribution. The numerical study was conducted using a commercial ANSYS CFD software. The experimental results of two test cases, from the literature and from the current experimental study, were used to validate the CFD software. The simulation results, obtained by the CFD software, were found to be in good agreement with the experimental results. Three typical five bladed turbines were used in this study. Various two turbine and three turbine configurations were examined experimentally and numerically to reach the optimum configuration in terms of power coefficient.
