En este trabajo se analiza el problema de la radiación cuerpo negro considerando acción 4D efectiva proveniente 6D un campo norma libre en una geometría no factorizable, donde las dos dimensiones extra son compactas, pero con diferente topología. Nuestro punto partida es descomposición Kaluza-Klein Maxwell sectores 4D. El primer sector contiene sin masa, mientras que segundo produce conjunto in...

A multiple-relaxation-time discrete Boltzmann model (DBM) is proposed for multicomponent mixtures, where compressible, hydrodynamic, and thermodynamic nonequilibrium effects are taken into account. It allows the specific heat ratio Prandtl number to be adjustable, suitable both low high speed fluid flows. From physical side, besides being consistent with Navier-Stokes equations, Fick's law Stef...

We compare the adsorption properties of intact supported silicalite membranes with those of silicalite powder and of alumina supports using nitrogen and argon as adsorbates at 77 K. We disentangle contributions from the membrane and support and find that the support contributes significantly to the total quantity adsorbed due to its relative thickness. The micropore-filling regions of the adsor...

In this present study, volume of fluid method in OpenFOAM open source CFD package will be extended to consider phase change phenomena with modified model due to condensation and boiling processes. This model is suitable for the case in which both unsaturated phase and saturated phase are present and for beginning boiling and condensation process needn't initial interface. Both phases (liquid-va...

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, ...
