Opis:: This paper presents results of the design analysis of a Tesla bladeless turbine intended for a co-generating micro-power plant of heat capacity 20 kW, which operates in an organic Rankine cycle on a low-boiling medium. Numerical calculations of flow in several Tesla turbine models were performed for a range of design parameters. Results of investigations exhibit interesting features in the distribution of flow parameters within the turbine interdisk space. The calculated flow efficiency of the investigated Tesla turbine models show that the best obtained solutions can be competitive as compared with classical small bladed turbines.

Tytuł:: Hydrodynamical loads on a floating dock towed in sea conditions

Opis:: Response amplitude operators (RAOs), short-term and long-term predictions of hydrodynamical response of a floating dock towed in conditions of Baltic and North Sea, are presented and analyzed. The research was focused on : heave and pitch motions, dynamic pressure induced in different parts of the dock’s bottom, vertical bending moment and resistance of the dock towed in head seas. The RAOs of the considered responses were determined by means of model tests and/or a computer calculation program based on strip theory. Discrepancies between so obtained values of the characteristics and predicted values of relevant responses, calculated on their basis, were indicated.
