Diffusion models implementation in hypersonic flow regimes
Gür, Berk; Eyi, Sinan (null; 2017-09-20)
This study highlights the diffusion phenomena in hypersonic flow regimes. It is an important event that has to be define in the flow field solutions. There are two famous diffusion model; Fick’s Law of Diffusion and Stefan-Maxwell Diffusion Equation. Both are included in the calculations. The model differences are observed both physically and mathematically. Finally, their results are examined for each of the species.

Diffusion equation modeling for sound energy flow analysis in multi domain structures
Gül, Zuhre Su; Odabaş, Erinc; Xiang, Ning; Calişkan, Mehmet (Acoustical Society of America (ASA), 2019-04)
This study investigates reliable models and methods to be applied in sound field analysis of multidomain structures. The case structures are two monuments, namely, Suleymaniye Mosque and Hagia Sophia in Istanbul. These are both multi-volume spaces with many smaller sub-volumes coupled to each other by coupling apertures in form of arches. A key concern of the study is to examine energy flow decays and understand the mechanism of multi-slope sound energy decays. The methodology involves diffusion equation mo...
Diffusion in Hypersonic Flows
Gür, Hilmi Berk; Eyi, Sinan (Nova Science Pub Inc, 2020-10-01)
In hypersonic flows, air goes into chemical reaction due to high temperature. Therefore, in addition to the Navier-Stokes Equations, chemical reaction equations need to be solved to analyze hypersonic flows. A model may be need to simulate the diffusion phenomena among chemical species. It is possible to implement Fick's Law of Diffusion as well as Stefan-Maxwell Diffusion Equation. Basically, in Fick's Law of Diffusion, the driving force is the species concentration differences. This method is similar to t...
Diffusion Resistances and Contribution of Surface Diffusion in TAME and TAEE Production Using Amberlyst-15
Doğu, Timur; Boz, Nezahat; MÜRTEZAOĞLU, KIRALİ; DOĞU, GÜLŞEN (2003-01-01)
Effective diffusivities and adsorption equilibrium constants of methanol, ethanol and 2-methyl-2-butene (2M2B), in Amberlyst 15, were evaluated from batch adsorption experiments. Moment expressions derived for different models involving diffusion resistances in the macropores and within the gel-like micrograins were used for the evaluation of effective diffusion coefficients. Contribution of surface diffusion to diffusion flux within the macropores was found to be quite significant. Also, it was found that ...
