The purpose of this paper is to present the experimental performance tests of a family of turbine ventilators designed, using the momentum-blade element theory. The turbine ventilator is designed such that multiple blade configurations and different geometric angles of attack were varied. A total of 108 turbine configurations were tested. The experimentation process is carried out with an open section Low-Speed wind tunnel at the Universidad de los Andes in Bogota´, Colombia. The power coefficient CP and torque coefficient CT curves were derived from rotational speed data measured using a 100 pulses-per-second optical encoder. The best configuration achieved consists of a 16 blades turbine with a −70° geometric angle of attack which has the following maximum values: CP of 0.18, CT of 0.82. This paper outlines the results obtained during a four month (150 hours - 3 academic credits) length undergraduate research project completed at the Universidad de los Andes.
