Can logical framework and pseudo-code be used to model wind turbine impeller?
Therefore, one high efficient approach for geometric modeling of wind turbine impeller is proposed by this study, and the validity of logical framework and pseudo-code of each part correspondingly is confirmed through several applications upon modeling of impeller, with time-efficient to shape in the process-designed.
What is the difference between an impeller and a turbine?
There is a tendency to think of the impeller as a hydraulic pump and the turbine as a hydraulic motor. In truth, the function of the impeller is to pump (import momentum to) a fluid, and the function of the turbine is to convert fluid energy back into mechanical energy.
What are the different types of turbine impellers?
In the present work, laser-doppler anemometry measurements as well as CFD simulations have been performed for the flow generated by various impellers, namely disc turbine (DT), a variety of pitched blade down flow turbine impellers varying in blade angle (Standard PBTD60, 45 and 30) and hydrofoil (HF) impeller.
Can 3D model of impeller for wind turbine improve CFD analysis?
It is a very important fundamental work that 3D-model of impeller for wind turbine can be achieved precisely, in order to enhance the credibility of CFD analysis in subsequent calculations. However, the current studies do not emphasize closely on the modeling with time-saving and high efficient.
