A mathematical model of film cooling of turbine blades under the conditions of the formation of a film on a punched surface having blank damping cavities is suggested. Based on numerical investigation with the use of the proposed model, the possibility of a substantial increase (under the analyzed conditions ensuring a decrease in the adiabatic wall temperature by 200 K) in the efficiency of film cooling due to partial laminarization of a turbulent boundary layer on the punched surface has been revealed.
