▪Reaction-diffusion equations are differential equations for interpretation of chemical reaction and diffusion phenomena, and they can be applied to analysis of chemical processes as well as spreading of viral infect to human body or city. In our laboratory, modeling of batch and continuous catalytic reactors are carried out by solving reaction-diffusion equations to compare the results with experimental data.

▪Catalytic pellets and adsorbents with cylindrical or core-shell morphologies are studied for reaction and separation processes by analytical solutions and numerical methods using commercial softwares such as COMSOL or MATLAB. Analytical solutions are obtained by integral transform method, and approximate solutions are also studied by perturbation method.

▪Modeling targets: core-shell pellets, core-shell adsorbents, immobilized enzyme reactors, photocatalytic reactors, CO2 absorption by emulsion system, heterogeneous reaction of solid and fluid, dynamic catalyst, spread of viral infection
