in this study, the modeling of hydrogen production process in microreactors by methanol-steam reforming reaction is investigated. the catalytic reaction of methanol-steam reforming producing hydrogen is simulated considering a 3d geometry for the microreactor. to calculate diffusion among species, mixture average correlations are compared to stephan-maxwell equations. the reactions occurring in...

a foodstuff response evaluating at different forces such as shear, compress, tensile and chewing force is in fact product texture evaluating which is relying on rheological characteristic. in this research, the relaxation behavior of various chicken parts was perused based on generalized maxwell model at different regimes. the effects of three types of treatments as control (without additives),...

Linear stability of double diffusive convection of Darcy-Maxwell fluid with Soret and Dufour effects is investigated. The effects of the Soret and Dufour numbers, Lewis number, relaxation time and solutal Darcy Rayleigh number on the stationary and oscillatory convection are presented graphically. The Dufour number enhances the stability of Darcy-Maxwell fluid for stationary convection while it...

The governing equations of three dimensional elasticity problems include the six Beltrami-Michell stress compatibility equations, the three differential equations of equilibrium, and the six material constitutive relations; and these are usually solved subject to the boundary conditions. The system of fifteen differential equations is usually difficult to solve, and simplified methods are usual...

to evaluate the effect of replacing the almond meal on viscoelastic properties of rice cake, stress relaxation test was carried out. stress relaxation test were conducted using a texture analyzer machine. constants of the peleg - normand and the extended maxwell model for variables were calculated. the results showed that with increasing strain rate increased amount of k1, k2 and decay forces, ...

This study evaluated the performance of the Maxwell 16 System (Promega) for extraction of influenza virus (flu-v) RNA from diverse samples compared to a classical manual method (QIAamp Kit, QIAGEN). Following extraction by the two methods, all samples were analyzed by Real-time RT-PCR. Results revealed that the use of the standard Maxwell 16 protocol (Maxwell 16-S) resulted in good linearity an...

In this paper we propose and investigate some edge element approximations for three Maxwell systems in three dimensions: the stationary Maxwell equations, the time-harmonic Maxwell equations and the time-dependent Maxwell equations. These approximations have three novel features. First, the resulting discrete edge element systems can be solved by some existing preconditioned solvers with optima...

In this article, the electro-osmotic flow of Oldroyd-B fluid in a circular micro-channel with slip boundary condition is considered. The corresponding fractional system is represented by using a newly defined time-fractional Caputo-Fabrizio derivative without singular kernel. Closed form solutions for the velocity field are acquired by means of Laplace and finite Hankel transforms. Additionally...
