Development of low-power high-speed turbogenerator

Abstract

Mankind always needs heat and electricity. Renewable energy sources utilized via organic Rankine cycle (ORC) which use turbogenerators as a power machine belonging to sustainably developing areas in the energy sector. ORC plants use waste heat, pellet fuel, or waste as primary sources of energy. Full-scale development of such machines is hampered by the high cost of equipment for implementing the cycle and iterative revision of the turbogenerator.

This work proposes to carry out model experiments over machines on the gas-dynamic test stands. A roadmap for designing an experimental high-speed low-power turbogenerator is presented. A turbogenerator with a rotational speed of 150 000 rpm and a power of 1 kW has been studied from electromagnetism, fluid dynamics, and mechanics' points of view
