Large Eddy Simulation of combustion instabilities in a lean partially premixed swirled flame [PDF]

, 2012
This paper investigates one issue related to Large Eddy Simulations (LES) of self- excited combustion instabilities in gas-fueled swirled burners: the effects of incom- plete mixing between the gas injection and the combustion chamber.

From Single to Multi‐Glass/Ceramic Microarchitectures via Two‐Photon Lithography

Advanced Optical Materials, EarlyView.
Two‐photon lithography enables precise oxide microarchitectures. A transition is made from single to multi‐glass/ceramic materials by integrating spatially varied compositions via fluidic photoresin exchange. Low‐temperature annealing and optical characterization (i.e., cathodoluminescence, fluorescence microscopy) reveal how post‐treatment affects the

Multi‐Objective Optimization of a Climate‐Responsive Green Hydrogen‐Based Multi‐Generation System with Advanced Energy Storage and Heat Recovery

Advanced Sustainable Systems, EarlyView.
A novel hydrogen‐based multi‐generation system integrates CAES, PEME, and ORC for climate‐responsive power generation. Using response surface methodology, the system is optimized for energy efficiency, emissions, and cost. Results highlight its strong performance in temperate climates and its potential for modular, scalable deployment.
