This paper details the use of nanosecond repetitively pulsed discharges to attenuate combustion instabilities in a 14 kW swirl-stabilized methane/air combustor. The combustor exhibits large-amplitude pressure oscillations ranging from 1 to 4% of the

A novel high-swirl reactor ANJEVOC-CP (annular jet vortex chamber for combustion pyrolysis) was designed for producing high-value chemicals such as alkynes and olefins from natural gas. In such a s...

The precessing vortex core (PVC) is a self-excited flow oscillation state occurring in swirl nozzles. This is caused by the presence of a marginally unstable hydrodynamic helical mode that induces precession of the vortex breakdown bubble (VBB) aroun

In this paper, we examine the role of reduced chemical kinetics mechanisms in predicting the flow structure using multi-dimensional large-eddy simulations in complex geometries. We investigate the ...

The stabilization of turbulent lean premixed flames in a backward-facing step combustor is investigated using large eddy simulations, with a reduced 2-step reaction kinetics mechanism and one of two detailed mechanisms. Although all reaction mechanis

A small-to medium-scale, mobile torrefaction system has the potential to improve the economics of biomass torrefaction and expand its deployment in decentralized, rural areas. In order to simplify the reactor design for deployment in these contexts,

Two key flame macrostructures in swirling flows have been observed in experiments of oxy-combustion (as well as air-combustion); as the equivalence ratio is raised, the flame moves from being stabilized on just the inner shear layer (Flame III) to ge

Water and energy systems have often been treated as separate “silo” systems over the entire pathway from production to consumption. However, their close interdependence requires some perspective of the water-energy nexus (WEN), especially in regi
