Computational Study of Leading Edge Tubercles on Propeller Performance

Experimental investigation on the effect of Leading Edge Tubercles on the Performance of Marine Propellers in fully wet condition

“…However, thrust and torque data are not available and a comparison, at least qualitative, with the present ones can not be performed. In this regard, the computational analysis described in (Joshi et al, 2020), carried out for aeronautic propeller similar to (Butt and Talha, 2019) for only a single modified geometry, confirmed that the leading edge tubercles improve the efficiency for all the range of advance coefficient tested, although the thrust and torque were lower with respect to the original configuration. These outcomes qualitatively confirm the findings drawn for wings and tidal turbines (Shi et al, 2019b).…”
