Abstract
The publication is devoted the decision of an actual problem increase efficiency operation of ship diesel engines by perfection processes greasing of cylinders. It is interesting to consider the simultaneous movement of the liquid film of oil and gas flow in the case when the latter is turbulent. Estimating the speed distribution in this case is quite a time consuming task. Therefore, only its first stage is considered here, which consists in obtaining an asymptotic solution for large values of x. The prospect of practical application of two-phase gas-liquid film motion is quite attractive, especially in the case of the same direction, when the stabilizing effect is manifested. A quantitative description of such motion is considered exhaustive if the components of the velocity vector, the oil pressure, and the film thickness are determined. These characteristics are obtained by solving the basic equations of the mechanics of continuous media, including the equations of momentum transfer, continuity and macroscopic balance. Keywords: ship diesel engine, greasing system, greasing channel, greasing process, cylinder, piston, a piston ring.
