    Analysis of mechanical losses in the working chamber of rotary vane machines by N. A. Raikovsky, V. L. Yusha, K. I. Kuznetsov, V. A. Korenev, V. S. Karpus

    Published 2020-03-01
    “…It is established that the smallest friction loss is provided by lubricating the cylinder with water, while the values of the friction coefficient obtained by processing the results indicate the presence of the hydrodynamic lubrication regime. Unexpectedly large values of friction power losses are obtained when oil is used as a lubricant, which is primarily due to high hydromechanical losses, which, according to preliminary estimates, can reach 70%. …”
