The fixed-pitch straight-bladed vertical axis wind turbine (SB-VAWT) is one of the simplest types of wind turbine. The overall cost of the SB-VAWT will mainly depend on judicious choice of multiple design parameters. An attempt has been made in this paper to analyze the influence of three design parameters related to smaller-capacity fixed-pitch SB-VAWT with the help of a computational scheme. The three design parameters are: (i) solidity, (ii) aspect ratio and (iii) blade pitching. Affect of these parameters are analyzed for a SB-VAWT equipped with a special purpose airfoil “MIVAWT1” which has been designed for a smaller-capacity fixedpitch SB-VAWT. It has been demonstrated in this paper that proper selections of these three parameters are important for a cost-effective smaller-capacity SB-VAWT which can be considered as a candidate for urban and off-grid rural applications.
