This paper describes the passive flow control of fluid in the downstream direction of the circular tube and in tube banks by means of splitter plate. Heat transfer and pressure drop depend on complex flow pattern of fluid in tube banks, whereas pressure drop linked directly with the fluid pumping capacity. A primary focus is to review experimental, analytical and numerical works that had been c...

Active Queue Management (AQM) is the process of signaling Transmission Control Protocol (TCP) sources from core routers with the objective of managing queue utilization and delay. AQM methods can be classified into two main classes, namely, non-control theoretic-Random Early Detection(RED) and its variants and control theoretic-Proportional (P), Proportional Integral (PI) controllers. Shortcomi...

This study analyzes the characteristics of alumina (Al2O3)/water nanofluid to determine the feasibility of its application in an air-cooled heat exchanger for heat dissipation for PEMFC or electronic chip cooling. The experimental sample was Al2O3/water nanofluid produced by the direct synthesis method at three different concentrations (0.5, 1.0, and 1.5 wt.%). The experiments in this study mea...

Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evalu...

Background and Aim: Evaluation of the performance of these products is mainly based on their efficiency in numerical removal of particles in the range of different sizes. While the most important features of filters are the dust holding capacity, and the ability to remove the mass of particles with different densities, fewer studies have addressed this issue. Therefore, the present study evalua...

Sand fences are widely applied to prevent soil erosion by wind in areas affected by desertification. Sand fences also provide a way to reduce the emission rate of dust particles, which is triggered mainly by the impacts of wind-blown sand grains onto the soil and affects the Earth's climate. Many different types of fence have been designed and their effects on the sediment transport dynamics st...

Аннотация: В статье анализируются социально-экономические последствия развития дропшиппинга – новой формы организации продаж, стремительно завоевывающей российский рынок. Дропшиппинг открывает огромные перспективы не только для простых людей, но и для российских производителей, которые при правильном использовании возможностей дропшиппинга могут с минимальными затратами получить прямой доступ к...

We examine giant graviton with magnetic flux q in type IIA pp-wave background and find that it can move away from the origin along x4 direction in target space satisfying a nontrivial relation Rx4 = −q. This constraint is also investigated in a system of N D0-branes and it is observed that x4 enters into fuzzy algebra as a fuzzy parameter. The nontrivial relation can be regarded as a complement...
