نویسندگان
چکیده
An improved consistent soot nucleation model was proposed and tested on ethylene counterflow flames at different strain rates. The main objective of the is to capture correct rate sensitivity broaden applicability aerosol part with gas-phase kinetic mechanisms. Due uncertainties associated experimental measurements quantitative volume fraction (SVF), approach’s effectiveness mainly investigated qualitative behavior in terms sensitivity. Starting from a dimer-based available literature, inception described as heterogeneous collisions polycyclic aromatic hydrocarbons (PAHs) forming an intermediate dimer. Such justifies inclusion small precursors that conciliate satisfactory reproduction SVF rate, while retaining accuracy prediction. condensation rates sensitivities are found be regulated by presence dimer maintain right balance upstream dimerization process. collision helps generalize procedure makes more adaptable Details about temperature-dependent sticking coefficients also provided pivotal for synergistic prediction trends PAHs rate. integration important features allows generalized free empirical corrective factors, capturing Its ease implementation low computational cost make it suitable turbulent flame simulations.Copyright © 2022 American Association Aerosol Research

Transient soot dynamics in turbulent nonpremixed ethylene–air counterflow flames
The dynamics of soot formation in turbulent ethylene–air nonpremixed counterflow flames is studied using direct numerical simulation (DNS) with a semi-empirical soot model and the discrete ordinate method (DOM) as a radiation solver. Transient characteristics of soot behavior are studies by a model problem of flame interaction with turbulence inflow at various intensities. The interaction betwe...
متن کاملThe self-consistent bounce: an improved nucleation rate
Abstract We generalize the standard computation of homogeneous nucleation theory at zero temperature to a scenario in which the bubble shape is determined self-consistently with its quantum fluctuations. Studying two scalar models in 1+1 dimensions, we find the self-consistent bounce by employing a two-particle irreducible (2PI) effective action in imaginary time at the level of the Hartree app...

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
