Compressible CFD Code For Wind Turbine Simulation 2
|Principal Investigator(s)||Dr. George N. Barakos|
This project builds on the outcomes of 3C4WTS DECI project that took place last year and attempts to demonstrate the use of large-scale paralle CFD for the analysis of very large scale wind turbines. The need for clean, green energy is currently pushing the limits of what wind turbine manufacturers can pr oduce and a tendency is established for large scale wind turbines able to produce many MWatts of power. The detailed aerodynamic design of these turbines is yet to be defined and accurate prediction of the power output of new designs is top priority of any Wind Turbine manufacturer. Unfortunately, the inter action of the blades of the rotor with the tower is a difficult problem for analytical techniques and CFD is perhaps the only method with enough fidelity t o available to engineers. The work carried out by Liverpool during 3C4WTS demonstrated the potential of the in-house WMB solver and produced solutions for full wind turbines for the first time in the UK. The current project is aiming to deliver design guidelines regarding the maximum wind turbine diameter wh ich is both feasible and economically viable. Massively parallel computations are needed for the detailed aerodynamic analysis of these new machines. How ever, by computing the detailed turbulent flow field around the turbine’s blade and pylon and by resolving turbulent structures via the Detached Eddy Simulation technique smaller, more efficient engineering tools can be developed which will enable engineers to improve their designs and consequently resu lt in an environmentally friendly and economic source of electricity. To extract the necessary physics and understanding a small number of large CFD comput ations are necessary.
