As a sequel to the first and second reports of the present series of experiments intended to gain knowledge on the effect of surface roughness on hydromechanical characteristics, particularly cavitation performance, the author has this time taken up the case of striations in the direction parallel to the chord, to determine their effect on cavitation efficiency and profile performance in general, for comparison with that of spanwise striations which were the subject of the preceding two reports.
