Three-dimensional simulations of laminar flame propagating downwards the vertical surface of a rigid polyurethane slab heated by a radiative panel are presented and compared with the measurement data. The gas-phase model (ANSYS Fluent) allows for finite-rate volatile oxidation, soot formation and oxidation, emission, transfer, and absorption of the...
In this work, an optical emission-based two-color method was experimentally investigated for the measurement of surface temperatures of different types of fly ash samples using a CCD camera. A heating system consisting of a Hencken flatflame burner, a narrow piece of stainless steel wire mesh to separate the flame and the ash samples to be studied,...

Experimental study and three-dimensional simulation of warming up, ignition, and subsequent burning out of the composite material impacted by the attached Bunsen burner flame is presented. The specimen is the fiberglass-reinforced composite with the epoxy resin binder. In the experiment, vertical specimen was located above the laminar diffusion fla...
Coal char formation depends on its precursor properties and pyrolysis time-temperature history that has a significant impact on subsequent coal conversion processes and desired tar products. With the intention for getting comprehension of char/soot formation in coal pyrolysis, a simulation strategy combining the pyrolysis simulation for raw coal mo...

This work is focused on the development of planar in-situ laser-based methods serving for the mapping of soot precursors and soot particles in hash combustion conditions. We target the soot molecular precursors and particulates because there are still unanswered questions related to the mechanisms leading to the formation of soot particles and thei...

Plastic packaging typically consists of a mixture of polymers and contains a whole range of components, such as paper, organic residue, halogens, and metals, which pose problems during recycling. Nevertheless, until today, limited detailed data are available on the full polymer composition of plastic packaging waste taking into account the separabl...

AbstractTransient dynamics of formation and extinction of methane- and ethylene-fueled flames above the flat porous burner in an oxidizing atmosphere is numerically investigated. The simulated scenarios replicate the experimental conditions of the BRE (Flamenco) project of the ACME program focusing on combustion research in microgravity. The 3D uns...
