CFD Study About an Archimed Wind Mill

This study consists of a numerical simulation of the air flow on a new domestic wind turbine of the Archimedean type invented by a Dutch engineer in 2006; it takes the form of a repeated nautilus shell. this wind turbine is a little different from that of Marinus Mieremet in its design where the helicoidally curve is traced according to a data file, in our case the helicoidally curve is conical with angle of 30°, begins with a 5 cm of diameter (diameter of the rotation shaft) with a pitch of 1.25 m, this helix undergoes a circular repetition of 3 times. This wind Mill has given good results regarding the efficiency and the power compared to its lightness and installation cost for an average wind velocity of 8 m/s. The CFD study allowed obtaining the total pressure field, velocity field, velocity vectors, and streamlines around this Archimed Wind Mill (AWM). The behavior this flow is predicted. The force, torque and speed of rotation are extracted. And at the last the power of AWM is calculated by the theory of Betz limit or by the formula of torque. And therefore it is recommended for domestic use.
