Applied Thermal Engineering, 2020
To improve thermophotovoltaic system efficiency, a porous media combustor with a bluff-body as the flame holder was proposed. A two-dimensional numerical simulation of premixed hydrogen/air combustion inside a planar porous media channel with the local ...

Harvest wind energy from a vibro-impact DEG embedded into a bluff body
Energy Conversion and Management, 2019A novel wind energy harvester is proposed and studied in this paper. The system contains a vibro-impact (VI) dielectric elastomer generator (DEG) that can convert vibrational energy into electrical one through the impacts of a rigid ball inside.

Effect of hydrogen enrichment on swirl/bluff-body lean premixed flame stabilization
, 2020This paper reports the mechanism of hydrogen enrichment in stabilizing swirl/bluff-body CH4/air lean premixed flame. Large Eddy Simulation (LES) coupled with Thickened Flame (TF) model was performed to resolve the turbulent reacting flow.

Effect of non-uniform inlet profile on the combustion performance of an afterburner with bluff body
, 2020The quenching problem caused by the inlet distortion of the combustor during emergency attitude adjustment of an aircraft has not been adequately solved by a lack of experimental evidence in non-uniform inflow.

Wake Instabilities Behind Bluff Bodies
2006The observation by Benard of a vortex street in the wake of a circular cylinder has been commonly associated with the stability analysis of the double alternate street proposed by von Karman. After a short historical review of these studies, we present the main progress in understanding this instability during the last decade.
