Description:

In this project, an atypical resistance rotor of a vertical axis rotor as a small wind energy turbine is to be aerodynamically investigated and optimised in a flow simulation. In this report the results obtained from the flow simulations of the single and two rotor setup, as well as the results from the flow simulations of a single blade, are presented. The geometry of the rotor and blades is the base geometry for further optimisation. All simulations are performed with one specific tip speed ratio. The base geometry for slat and baffle can be calculated based on experience gained in previous studies. It was found in previous experiments that a rotor with 42% overlap (area that occupies the wings of the total circumference) is always started. Those experiments have also shown that a rotor with 36.5 % overlap has a higher power coefficient at low wind speeds, at higher wind speeds, the rotor with 42 % overlap has a better power coefficient. Based on those first investigations the optimisation of the blade and rotor geometry will be carried out later in this project.
