Mathematical Modeling of Nanoparticle Cloud Combustion Incorporates the Effects of Particle Phase Change within the Reaction Zone of a Non-Premixed Combustion System Operating in a Counterflow Configuration [PDF]

Iranian Journal of Chemistry & Chemical Engineering
In this study, the multi-stage edge combustion of a particle cloud was modeled, and the effect of changing the fuel type on the change in the triple flame propagation velocity was considered.

Effect of the Reynolds and Lewis number to the fuel droplet vaporization

Thermal Science, 2023
In this work we present the effect of Reynolds and Lewis numbers on the fuel droplet vaporization of n-heptane. This study allows us to fully understand the vaporization phenomenon of fine fuel droplets (spray) in energy systems in order to improve combustion efficiency, reduce the formation of pollutants and unburned materials such as CO and NOx.

Combustion mechanism of propane-air swirling premixed flame near lean flammability limit

Journal of Thermal Science and Technology
This study investigated a premixed propane-air flame in a partially tapered swirl burner. Experimentally, we found that a flame resembling a morning glory flower formed at an equivalence ratio near the lean flammability limit.

Effects of radiation, curvature, and preferential diffusion on the extinction of laminar non-premixed flames

AIP Advances, 2022
The combined effects of radiative heat loss, curvature, and preferential diffusion on laminar non-premixed flames (or flamelets) are investigated in this work by using asymptotic analysis.

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...
