During its near-ground hovering phase a Short Take-Off and Vertical Landing (STOVL) aircraft creates a complex three-dimensional flow field between jet streams, the airframe surface and the ground. A proper understanding and numerical prediction of this flow is important in the design of such aircraft. In this paper an experimental facility, used to gather validation data suitable for testing C...

The development of high-performance thermal systems has increased interest in heat transfer enhancement techniques. The application of additives to heat transfer liquids is one of the noticeable effort to enhance heat transfer. In this paper two-dimensional unsteady incompressible nanofluid flow in a confined jet at the laminar flow regime is numerically investigated. The Mixture model is consi...

Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

Many works have considered two-dimensional free-surface flow over the edge of a plate, forming waterfall, and with uniform horizontal far upstream. The is assumed to be steady irrotational, whilst fluid inviscid incompressible. Gravity also taken into account. In particular, amongst these works, numerical solutions for supercritical flows been computed, utilising conformal mappings as well seri...

Human desires toward the heavens had been continued after Tower of Babel. Many high-rise buildings were constructed with technological progress in the 20 century. The tallest skyscraper of the world is Burj Khalifa (Dubai, UAE) with a height of 828 meters. Kingdom tower (Jeddah, KSA) would be tallest building with 1,000 meters about 2019 (1). Skyscrapers have lots of problems in terms of disast...

introductionmany aspect strongly influence regional climate includes localized surface processes, large-scale patterns, especially mid and upper level tropospheric circulation and many factors control precipitation in the west of iran includes location of emigrate westerly winds systems, jet streams location, humidity flux and topography. upper tropospheric jet stream constitutes a significant ...

Destabilized nanobodies can be used to deliver fluorescent proteins and enzymes to specific targets inside cells.

rade control structures are used to control bed erosion in steep small rivers mostly in the mountains. scour downstream of this structure can lead to failure. over the past years, the effect of different variables on this phenomena have been studied, however the effect of upward seepage which is common due to head difference of the banks water table or water surface level between the upstream a...
