The transitional intermittency is investigated in the zero pressure gradient boundary layer developing on the surface covered with sand paper. The transitional intermittency factor distribution is derived by means of the TERA method. Evaluated are the probability density function and the conditioned probability density functions of the wall friction, relevant moments and the mean residence time of the wall friction in laminar and turbulent state.
