Incompressible boundary-layer transition has been analyzed using a second-order closure turbulence model. With no transition-specific modifications, the turbulence model predicts salient features of incompressible, zero-pressure-gradient boundary-layer transition including sensitivity to freestream turbulence and surface roughness, transition width, and transitional velocity profiles. With transition modifications based on linear stability theory, the model accurately predicts transition sensitivity to surface heat transfer, pressure gradient, and suction. With no further modifications, transition predictions have been made for several hydrodynamic bodies, including effects of surface heating. Author
