The complexity of wavy film flows results in a high computational cost for a direct numerical simulation. Simplified models are therefore attractive alternatives for engineering design calculations. An incremental approach for the identification of transport models in wavy film flows is presented here. The proposed strategy decomposes the identification problem into a series of sequential, comp...

The main objective of current study is investigation on thermo-hydraulic behavior nanofluids in a sinusoidal wavy channel as novel geometry under influences thermophoresis and Brownian motion. Differential quadrature method optimal homotopy asymptotic scheme have been employed to solve the momentum, continuity, energy nanoparticle fraction equations. validity proposed approaches evaluated by co...

Wilson loops which are small deviations from straight, infinite lines, called wavy lines, are considered in the context of the AdS/CFT correspondence. A single wavy line and the connected correlation function of a straight and wavy line are considered. It is argued that, to leading order in “waviness”, the functional form of the loop is universal and the coefficient, which is a function of the ...

The volume flow rates of Eyring-fluids inside the wavy-rough nanoannulus were obtained analytically (up to the second order) by using the verified model and boundary perturbation method. Our results show that the wavy-roughness could enhance the flow rate especially for smaller forcing due to the larger surface-to-volume ratio and slip-velocity effect. Meanwhile, the phase shift between the out...

We use ab initio density-functional calculations to determine the interaction of a graphene monolayer with the Si(111) surface. We find that graphene forms strong bonds to the bare substrate and accommodates the 12% lattice mismatch by forming a wavy structure consisting of free-standing conductive ridges that are connected by ribbon-shaped regions of graphene, which bond covalently to the subs...
