One of the major advantages of circulating fluidized bed (CFB) combustors is their efficiency for the combustion of wide variety of solid fuels. From this point of view, in this study, the combustor efficiency has been defined and investigated for CFB biomass combustor based on the losses using a dynamic 2D model. The model is shown to agree well with the published data. The combustion efficien...

In this study, a 2D model for a CFB biomass combustor has been developed which integrates and simultaneously predicts the hydrodynamics, heat transfer and combustion aspects. Combustor hydrodynamic is modeled taking into account previous work. Simulation model calculates the axial and radial distribution of voidage, velocity, particle size distribution, pressure drop, gas emissions and temperat...

For some decades, efforts have been made to exploit nonsteady combustion and gas dynamic phenomenon. The theoretical potential of nonsteady-flowmachines has led to the investigation of various oscillatoryflowdevices suchas pulse detonation engines, wave rotors, pulse jets, and nonsteady ejectors. This paper aims to provide a progress review of past and current research in developing a particula...

This experimental investigation focused on the ignition and combustion characteristics of a tandem cavity-based scramjet combustor with side-by-side identical cavities. study utilized Pusan National University-direct connect (PNU-DCSC), which was capable simulating flight conditions at Mach number 4.0–5.0 altitudes 20–25 km using vitiated air heater (VAH). The tests were conducted under off-des...
