| Summary: | Today, in the spectrum of tasks solved by orbital spacecraft, there is a direction associated with an
increase in both functional and thermal power radiated by the thermal control system into outer space.
At thermal power more than 7 kW, there is a shortage of heat-radiating surfaces. The problem can
be solved in three directions: increasing the temperature of the radiating surface; unfolding additional
surfaces; utilization of thermal energy in the organic Rankine cycle. The key link in the implementation
of the cycle is the modeling and design of a low-potential jet microturbine. When modeling the
working process of such a turbine, a preliminary assessment of energy losses during the formation of
a circumferential flow at the impeller inlet is necessary. One of the parameters determining part of the
losses is the velocity coefficient φu
. This work is devoted to the theoretical substantiation and method
of experimental determination of the coefficient in the range of geometric and regime parameters of
the tangential supply of a subsonic centripetal turbine. |
