Influence of the axial turbine design parameters on the stator–rotor axial clearance losses
(Sage Journals, 2014)
The drive towards lower emissions in aerospace engines promotes more efficient and physically smaller engines. One way to decrease the size of the axial turbine is to minimize the distance between successive stator and ...
Performance and flow fields of a supersonic axial turbine at off-design conditions
(Institution of Mechanical Engineers, 2013)
The increasing demand of energy efficiency and the utilisation of small-scale energy sources require efficient, small and versatile turbines. Supersonic turbines have a high power density and therefore small size and fewer ...
Importance of the vane exit mach number on the axial clearance-related losses
(Sage Journals, 2016)
More efficient and physically smaller axial turbine designs are promoted to lower emissions and increase revenue. The physical size and the weight of the axial turbine can be minimised by adjusting the distance between ...
Numerical modelling of small supersonic axial flow turbines
(Lappeenranta University of Technology, 2010-08-25)
Supersonic axial turbine stages typically exhibit lower efficiencies than subsonic axial turbine stages. One reason for the lower efficiency is the occurrence of shock waves. With higher pressure ratios the flow inside the ...
Ylisoonisen yksivaiheisen aksiaaliturbiinin suunnittelu
(2006)
Tässä diplomityössä suunnitellaan yksivaiheisen turbiinin ylisooninen staattori ja alisooninen roottori, tulo-osa ja diffuusori. Työn alussa tarkastellaan aksiaaliturbiinin käyttökohteita ja teoriaa, jonka jälkeen esitetään ...
