On Cup Anemometer Rotor Aerodynamics

The influence of anemometer rotor shape parameters, such as the cups' front area or their center rotation radius on the anemometer's performance was analyzed. This analysis was based on calibrations performed on two different anemometers (one based on magnet system output signal, and the other one based on an opto-electronic system output signal), tested with 21 different rotors. The results we...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Mathematical Analysis of the Effect of Rotor Geometry on Cup Anemometer Response

The calibration coefficients of two commercial anemometers equipped with different rotors were studied. The rotor cups had the same conical shape, while the size and distance to the rotation axis varied. The analysis was based on the 2-cup positions analytical model, derived using perturbation methods to include second-order effects such as pressure distribution along the rotating cups and fric...

Wull{shape and Density Deviation

Recent results on sphere packings show a remarkable relation between dense nite sphere packings and concepts of crystallography, such as the Gibbs{Curie surface energy and the Wull{shape for ideal crystals and quasicrystals ((W2], W3], S], BB], BS1] and BS2]). The previous papers mainly considered applications. Here we prove some basic properties of the tools, in particular the density deviatio...

A virtual instrument for automatic anemometer calibration with ANN based supervision

A fully automatic anemometer calibrator intended for performing fast and accurate calibrations has been developed to fulfil the increasing demand and strict requirements of the wind energy industry. Different sensors are connected to a computer where a virtual environment acquires and processes the incoming signals and controls a wind tunnel, allowing the calibration of the anemometer at the pr...
