An experimental study has been made to evaluate various common methods of stimulating transition from laminar to turbulent flow in the boundary layer of two five-foot ship models. A hot-film anemometer is employed to determine the nature of the flow in the boundary layer. Qualitative analyses of the results of these hot-film surveys for a strut, sandstrips, pins and Hama Triangles, used separately, are compared with resistance measurements simultaneously taken. The results of this work show that the hot-film anemometer is an effective turbulence detection instrument on small ship models and indicate pins to be the most effective stimulator.
