제목 On The Influence of Physical Processes on the Pyrolysis of Single Tobacco Particle
초록 A mathematical model of the transient pyrolysis of single tobacco particle accounting for the physico-chemical processes is presented. The model considers pyrolysis of tobacco particle obeying four single-step Arrhenius kinetics, evaporation of water from tobacco following a mass-transfer- and rate-determined process, and the formation of carbonaceous residue. Physical processes account for convective, conductive and radiative heat transfer and velocity and pressure variations interior to the porous tobacco particle (Darcy’s law). Furthermore, physical properties such as porosity, permeability and thermal conductivity vary with the composition of the reacting medium. A comparison is made between the heat transferred to tobacco particle by convection and by conduction on a boundary. The model is implemented in commercially available computational fluid dynamics code, FLUENT, using user-defined-functions (UDFs).
