Features of the Design of a Self-Draining Solar Power Plant with an Active Element

Abstract

The calculation dependences for designing a self-draining solar power plant (SDSPP) with an active element in the form of a narrowing device of the Venturi tube are obtained. The calculation dependences for the transient modes in an SDSPP are analyzed from the point of view of the representations of the nonlinear nonequilibrium thermodynamics. It is shown that two steady operation modes of an SDSPP are possible: with and without a break of the jet. It is specified that both these modes merge when the consumption of the heat transfer fluid is equal to the critical value, for which the contraction ratio of the flow in the Venturi tube is defined, and differ when their values are higher than the critical value.
