...Despite the favourable performance noted in laboratory testing for the linked guide vane system, operating life and maintenance issues were confirmed with prototype testing of the self-pitching linked guide vanes in Vizhinjam, South India, by the National Institute of Chapter 2 41 Ocean Technology (NIOT) (Maeda et al. 1999)....

...It has been concluded through CFD analysis that a guide vane setting angle of 30º results in optimum performance (Setoguchi et al. 2001a, Abugihalia 2002) and this confirmed the experimental results carried out by Maeda et al. (1999)....

...An optimum ratio of major axis to minor axis of the elliptical curve of 3 was established by Maeda et al. (1995) and confirmed by Setoguchi et al. (2001b). This is derived from the optimum blade inlet angle which will be discussed in the next section....
