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...

BACKGROUND Hydatid disease is rare in the United States. Rarely the hydatid cyst can become infected with mycotic organisms, such as Aspergillus. We describe a young male who presents with clinical features of suppurative lung abscess whose workup diagnosed hydatid cyst complicated by Aspergillus co-infection. CASE PRESENTATION A 27-year-old Peruvian male was hospitalized because of fever, ch...

This article can be considered as an extension of the paper of Fukagata et al. Phys. Fluids 14, L73 2002 which derived an analytical expression for the constituent contributions to skin friction in a turbulent channel, pipe, and plane boundary layer flows. In this paper, we extend the theoretical analysis of Fukagata et al. formerly limited to canonical cases with two-dimensional mean flow to a...

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 ...

Ammonite shells have complex patterns of suture lines that vary across species. The lines are formed at the intersection of the outer shell wall and the septa. The wavy septa can form if the rear mantle of the ammonite, which functions as the template, has a complex shape. Previous hypotheses assumed that the rear mantle is like a flexible membrane that can be folded by some physical force. The...

The flow characteristics and vortex evolution behind a circular cylinder near wavy wall are studied using large-eddy simulation framework. Reynolds number based on the diameter D is Re = 1500, gap ratio G/ fixed to 1, slope S λ/2 k varies from 2 8 (where G distance between lower surface of crest, λ wavelength, wave amplitude). field characteristics, hydrodynamic coefficients, pressure distribut...

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...
