TL;DR: In this article, the NH 3 -air combustion power generation has been successfully realized using a 50kW class micro gas turbine system at the National Institute of Advanced Industrial Science and Technology (AIST), Japan.

TL;DR: Based on the global demand for carbon-free power generation as well as recent advances involving gas-turbine technologies, such as heat-regenerative cycles, rapid fuel mixing using strong swirling flows, and two-stage combustion with equivalence ratio control, a low-NOx NH3-air non-premixed combustor was developed by using a 50kWe class micro gas-to-power system at the National Institute of Advanced Industrial Science and Technology (AIST), Japan, for the first time.

TL;DR: In this paper, the effect of tip clearance on the aerodynamic characteristics of an unshrouded axial-flow turbine cascade under very low Reynolds number conditions was investigated and the results showed that tip leakage flow generated a large high total pressure loss region.

TL;DR: In this article, a 50kW class turbine system firing kerosene is selected as a base model and a standard combustor is replaced by a prototype combustor which enables a bi fuel supply of kerosenes and ammonia gas.

TL;DR: In this article, the authors review recent developments in plasma virtual actuators for flow control that can replace conventional actuators and achieve better aerodynamic performance for land and air vehicles as well as rotational machinery.
