Power Prediction of Tandem Wind Rotor: Applied on Different Climatic Zones

Abstract

The present study highlights a comparative numerical simulation of two geometric configurations of a three-bladed vertical axis wind rotor. The simulation was carried out for different wind speeds of the last year 2021 and applied on different climatic zones, Tiaret from Algeria and Nouadhibou from Mauritania. This simulation is useful to estimate the aerodynamic power of a new three-bladed tandem (biplane) geometry. The objective of this study is to predict the lift and the power coefficients in order to estimate the efficiency, according to the blades active surfaces of the two designs, monoplane three-bladed and three-bladed in tandem configurations. The results obtained by the simulation show relatively a significant agreement with the experiences and the 6DOF approach published previously. The efficiency of the tandem rotor is higher than the monoplane three-bladed rotor (Cp max = 0.46). The climatic zone of Nouadhibou (Mauritania) is the windiest during the year 2021 referring to the variation of the average measured wind speeds comparing to Tiaret zone. The installation of this new type of design at the zone of Nouadhibou is preferable in terms of the highest produced aerodynamic power
