Mathematical Model of Smoldering Combustion in a Carbonaceous Porous Medium Part 2 – Sensitivity Analysis of Model Parameters

Abstract

In this paper, we systematically evaluated the effects of model parameters on the linear burn rate (LBR) and temperature to control smoldering of a cigarette. Fifteen model parameters were identified as smoldering factors. Among them, the theoretical findings of the effects of the cigarette radius, packing density, and water content on LBR and the peak temperature agree well with the experimental results in the literature. The method presented in this paper is adequate, and the basic mechanism of the natural smoldering process of tobacco can be explained. We evaluated the effects of smoldering factors on the LBR and the peak temperature ( Tmax), and obtained the basic data for establishing a scientific means of limiting the smoldering process, that can replace conventional experience and the trial and error approach.
