Item type:Publication, Non-equilibrium numerical modeling for combustion of LPG within porous media(2019-11-01); ; Lilavivat, VisarnA numerical model for lean premixed combustion of LPG (70% propane and 30% butane) within a porous inert medium was developed. Experiments were conducted at three different firing rates at the equivalent ratios of 0.4 and 0.6. The model was developed with the thermal non-equilibrium concept between phases and validated with three cases of experimental results. The discussion of model calibration was undertaken by focusing on the effects of the extinction coefficient and convection heat transfer effective area. Comparisons were made of the temperature profile, as well as the peak temperature, with the calculated adiabatic temperature. The model agreed well with experimental results and was robust throughout three firing rates. Moreover, it was found that the two aforementioned thermal parameters had different roles in temperature distribution, which provided insight on flame front location and heat transfer between phases within the porous domain. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Numerical simulation of porous media combustion for high temperature heat exchanger(2018-08-14); ; Hanamura, KatsunoriThe purpose of this work is developing the numerical 1D model of porous media combustion for investigating porous media burner systems. The software is used to solve energy, mass transfer and chemical reaction equation of the combustion. The operating condition and property parameters, which mainly affect the functions and quality of the industrial burner design, such as the inlet velocity of the reactants, the equivalence ratio, the extinction coefficient and the thermal conductivity of porous media, will be investigated and validated with experimental data. For developing the procedure of experiment, three diameter sizes of porous media materials (5 mm, 10 mm, and 15 mm.) were used. As a result, the developed model will be used as a tool to explore temperature distribution of heat exchange to improve thermal performance and overall efficiency system. Moreover, this knowledge can be applied to design porous media burner systems for uniform temperature distribution operation.1
