Generalized interface models for transport phenomena: Unusual scale effects in composite nanomaterials

Multiple Solutions for Slip Effects on Dissipative Magneto-Nanofluid Transport Phenomena in Porous Media: Stability Analysis

In the present paper, a numerical investigation of transport phenomena is considered in electrically-conducting nanofluid flow within a porous bed utilizing Buongiorno’s transport model and Runge-Kutta-Fehlberg fourth-fifth order method. Induced flow by non-isothermal stretching/shrinking sheet along with magnetic field impact, dissipation effect, and slip conditions at the surface are...

Critical Phenomena in Multi-scale Models

The paper is devoted to the investigation of the relationship between slow integral manifolds of singularly perturbed differential equations and critical phenomena in chemical kinetics and laser models. We tried to consider different problems using the techniques of canards and black swans. The mathematical language of singular perturbations seems to apply to all critical phenomena even in the ...

Numerical Simulation of Transport Phenomena in Nuclear Cores

Wave Transport Phenomena in Systems with Generalized Parity-Time Symmetry

In this thesis, we utilize the properties of scattering systems obeying anti-linear symmetries in order to produce novel wave transport phenomena. We first explore systems with delicately balanced gain and loss mechanisms, which are invariant under parity and time (PT ) reversal symmetry. Using equivalences between electronic network theory and photonic circuitry, we show that such structures c...

Modeling Transport Phenomena in Selective Catalytic Reductant Catalytic Converter with NH3 as Reductant for NO Degradation

In the current study, reduction of nitrogen oxide from exhaust gas in the presence of NH3 as reductant on selective catalytic reductant (SCR) impregnated catalytic converter was simulated using Comsol© software. Mass transfer (one-dimensional) and heat transfer (three-dimensional) governing equations were taken into account to model the unsteady state behavior of the catalytic converter. Modeli...
