Investigation into the stability of low-inertia micro-grids
(2023-05-01)
This work examines the stability of low inertia micro-grids (MGs). The lack of inertia in such power electronics dominated grid is a pressing matter that directly impacts its operation and stability. The investigated MG ...
The aeroacoustics response and shear layer dynamics of confined cavities subject to low Mach number turbulent flow
(2023-04-01)
Cavities exposed to low Mach number flow in various engineering applications are often liable for generating flow-excited acoustic oscillations, resulting in large acoustic amplitudes and vibrations. This compromises the ...
Decommissioning considerations for molten salt type reactors
(2023-05-01)
Molten salt type small modular reactors are presently being developed as an option for providing electricity and alternative energy forms. The current proposed designs do not document how decommissioning will be addressed. ...
