dc.description.abstractThis study was conducted theoretically with the aim of investigating the effect of the straight blade angle change on the aerodynamic performance of the vertical axis wind rotor (VAWR). The work was done within the blade angle range of 25 degrees -85 degrees with an angular gradient of 20 degrees. A special name has been given to the VAWR concerned in this paper, where it was called Straight Slant Blades (SSBs). The so-called multi-stream tube (MST) model was modified to be suitable for SSBs. MST is an aerodynamic model, which was previously used to work on what is known as Darrieus and H-Darrieus vertical axis wind turbines. A computer program is designed and developed using Microsoft Visual Basic to be consistent with the objectives of this research. As for verifying the effectiveness of this program, its theoretical results were compared with previous laboratory results from other research studies as it proved its effectiveness in achieving satisfactory results commensurate with the objective of this study. This study is applied to four groups of different engineering designs for the SSB rotor, where each group is concerned with one of the geometric variables confined to the rotor height 2H, the rotor radius R, the number of rotor blades N, and the airfoil C. The results obtained are displayed as rotor power coefficient curves as a function of blade tip speed ratio. As it resulted in the ideal range for the angle of the blade between 45 degrees and 65 degrees, according to the rotor in this range, the value of maximum power coefficient Cp-MAX is at its maximum and the range of tip speed ratios is the highest in addition to the diminution of the problem of self-movement.en_US
