Bragg scattering at one-dimensional corrugated substrates allows to improve the light outcoupling from top-emitting organic light-emitting diodes (OLEDs). The OLEDs rely on a highly efficient phosphorescent pin stack and contain metal electrodes that introduce pronounced microcavity effects. A corrugated photoresist layer underneath the bottom electrode introduces light scattering. Compared to ...

In warehouse storage applications, it is important to classify the burning behavior of commodities and rank them according to material flammability for early fire detection and suppression operations. In this study, the large-scale effects of warehouse fires are decoupled into separate processes of heat and mass transfer. As a first step, two nondimensional parameters are shown to govern the ph...

The wetting of water on corrugated and flat hexagonal boron nitride (h-BN) monolayers on Rh(111) is studied within a hybrid quantum mechanics/molecular mechanics (QM/MM) approach. Water is treated by QM methods, whereas the interactions between liquid and substrate are described at the MM level. The electrostatic properties of the substrate are reproduced by assigning specifically generated par...

Abstract In the present work, a numerical investigation of Latent Heat Thermal Energy Storage system (LHTESs) is performed on vertical shell and tube geometry, made porous medium filled with phase change material (PCM). The LHTESs cylinder corrugated inner surface at constant temperature above PCM melting temperature; external there are heat losses to outside top bottom surfaces adiabatic. used...

Improving the produced fluid yield is an effective measure for realizing crude oil production capacity of offshore platforms. However, platforms employed in production, using narrow space platform to expand water treatment system a significant problem. In this study, highly efficient pre-treatment core tube was coupled with main cavity and secondary cavities (MCSCs) based on vane-type tubular s...

Abstract A wide range of studies was conducted to increase the heat transfer rate and reduce size cost shell tube exchangers (STHE). The paper’s contributions lie in its ability provide a comprehensive, up-to-date, systematic overview various methods available for enhancement STHEs, making it an essential resource researchers, engineers, practitioners field transfer. that researched overall coe...

Energy efficiency and the amount of refrigerant in heat exchangers used cooling systems has recently been an important research subject. In this study, order to compare analyze different types evaporators, industrial refrigerators were designed context, test setups accordance with TS EN ISO 23953-2 standard produced. R290 (propane) was as system. During experiment, temperature-pressure measurem...

response surface methodology (rsm) is a statistical method useful in the modeling and analysis of problems in which the response variable receives the influence of several independent variables, in order to determine which are the conditions under which should operate these variables to optimize a corrugated box production process. the purpose of this research is to create response surface mode...
