the study of interactions of jet into cross flow at different longitudinal and transverse angles ofjet was studied. the following components were designed and constructed: a low velocity windtunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jetinjection, and a spatial rake to measure the total pressure. the tests were carried out atlongitudinal (α...

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...

+ ve G) were countered with limited success by pressure suits, horizontal posture, etcUpward forces (i.e. ve G) were less well tolerated. Whereas the former caused first greying out due to loss of colour vision, then blacking out and final unconsciousnessi recovery usually took place on removal of the stress in good time. On the other hand* with negative G a red out occurred, leading to cerebra...

The paper considers heat transfer characteristics of thin film flow over a hot horizontal flat plate resulting from a cold vertical jet of liquid falling onto the surface. A numerical solution of high accuracy is obtained for large Reynolds numbers using the modified Keller box method. For the flat plate, solutions for axisymmetric jets are obtained. In a parallel approximation theory, an advan...

One of the world's major mineral dust source regions lies along the border between Iran and Afghanistan. In this studyit is hypothesized that a low-level jet may play in role in generating the intensity of this source region. The presence of alow-level jet east of the Seistan mountains is documented here for the first time. The jet exists mainly from May toSeptember and has a core at 850 mb. Ma...

Numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. However, most of them address the problem from  macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. The present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle leve...

When a positively buoyant vertical fluid jet directed downwards from its source impinges on a horizontal flat surface, the resulting flow is termed an “impinging fountain”. These flows arise in a number of practical situations, for example, in gas metal arc welding (GMAW). Developing a description of this flow presents the researcher with a number of challenges and forms the motivation for this...

In the first part the sh Lie structure of brackets in field theory, described in the jet bundle context along the lines suggested by Gel’fand, Dickey and Dorfman, is analyzed. In the second part, we discuss how this description allows us to find a natural relation between the Batalin-Vilkovisky antibracket and the Poisson bracket. (∗)Alexander-von-Humboldt fellow.
