| Popis: | Different methods of profiling the working cavity of the second stage of a volumetric hybrid piston power machine are considered. Profiling of the working chamber in order to achieve a constant velocity of the liquid piston and attain the maximal magnitude of the heat-exchange surface, as well as profiling of the surface of a working chamber consisting of a cone and cylinder are performed. Computational formulas in analytic form are obtained in order to create a profiled surface that satisfies the first two conditions. For the third condition criteria for estimating the efficiency relative to the maximal magnitude of the heat-exchange surface and relative to the deviation of the velocity of the liquid piston from some constant velocity of the liquid in the working chamber are developed. As a result of a numerical experiment forms of the working chamber that satisfy the first two conditions are established and it is proved that a conical surface is best for a working chamber consisting of a cone and cylinder. |
