Pyrolysis in Porous Media: Part 2. Numerical Analysis and Comparison to Experiments

Abstract

Only limited studies are available experimentally to investigate hydrocarbon fuel pyrolysis, which can be of practical interest for the active cooling of head loaded components in aerospace vehicles such as combustors in rocket engines. The numerical simulation is an additional way to investigate the related phenomena (heat and mass transfer with chemistry). After a first code validation with experiments based upon inert gases, the code is further extended towards permeation with reactive dodecane and a reasonable agreement is found. The experimental accuracy of the permeability's' determination is confirmed numerically to be within ± 30 %.

CFD Analysis of Free Convection in Non-Darcian Porous Medium and Comparison With Similarity Approach

“…In general, the governing equations used by ANSYS/FLUENT software. for the case of an isotropic porous medium and for a single-phase flow are given by (2), ( 3) and (4): see Refs, ANSYS Fluent User's Guide, (ANSYS Inc, 2011) and Gascoin et al (2013)).…”

Numerical heat transfer analysis of transcritical hydrocarbon fuel flow in a tube partially filled with porous media

“…Gascoin and his team have published work about the permeation, pyrolysis and coke formation of high temperature hydrocarbon fuel in a porous medium like metal foam [36][37][38]. However, the heat transfer enhancement is not the focus.…”
