In the present investigations heat transfer studies are made in three different types of corrugated plate heat exchangers having a length of 30 cm and width of 10 cm. The corrugated channel has a spacing of 5 mm. Three different corrugation angles are used in this study which are 30 0 , 40 0 and 50 0 . Water is taken as test fluid as well as the heating medium. The wall temperatures are measure...

We demonstrate an effective approach to realize excitation and outcoupling of the SPP modes associated with both cathode/organic and anode/organic interfaces in OLEDs by integrating dual-periodic corrugation. The dual-periodic corrugation consists of two set gratings with different periods. The light trapped in the SPP modes associated with both top and bottom electrode/organic interfaces are e...

The diffraction intensities of He atoms scattered from vicinal Cu~211! and Cu~511! surfaces have been measured with a high angular resolution over a wide range of incident energies from 8 to 82 meV. Closecoupling scattering calculations with a corrugated Morse potential were performed to obtain the corrugation parameters for the first three complex Fourier coefficients. The energy-dependent cor...

We consider the relative stability of parallel and perpendicular lamellar layers on corrugated surfaces. The model can be applied to smectic phases of liquid crystals, to lamellar phases of shortchain amphiphiles and to lamellar phases of long-chain block copolymers. The corrugated surface is modelled by having a single q-mode lateral corrugation of a certain height. The lamellae deform close t...

A radial line slot antenna (RLSA) in Fig.1 is a high-gain, high-efficiency and low-cost planer antenna, which was originally proposed for satellite TV reception at 12GHz band [1]. Recently this antenna has been designed for a space solar power system (SSPS) [2],[3]. Figure 2 shows the relationship between the slow-wave factor and the aperture efficiency. The slow-wave factor ξ is defined as ξ=λ...

Abstract This paper presents the results of a comprehensive assessment manufacture pipes with corrugated inner surface.

Abstract The expediency of replacing the corrugated ring a vascular stent with constant corrugation pitch by variable is being investigated. To describe change in corrugation, special function introduced. equilibrium and deformation equations were analyzed using asymptotic homogenization method. dependence radial stiffness on constructive parameters obtained. effectiveness design under consider...

Many studies have shown that the rail corrugation on small radius curve section of subway floating slab track is serious. And it seems to be different from common track. The structure must play an important role in generation and development corrugation. This paper measured a line Tianjin, including 2 structures, analyzed data by using international evaluation acceptance indexes results show in...

We report on a novel approach to determine the relationship between the corrugation and the thermal stability of epitaxial graphene grown on a strongly interacting substrate. According to our density functional theory calculations, the C single layer grown on Re(0001) is strongly corrugated, with a buckling of 1.6 Å, yielding a simulated C 1s core level spectrum which is in excellent agreement ...
