به منظور آزمایش و ارزیابی نازل های سمپاش های پشت تراکتوری ساخت ایران شش نوع از این نازل ها در سال 1377 در محل کارگاه گروه ماشین های کشاورزی، دانشکده کشاورزی، دانشگاه شهید چمران اهواز آزمایش شد. یکنواختی "دبی، الگوی پاشش ، همپوشانی و زاویه پاشش " مورد ارزیابی قرار گرفت . از یک نازل خارجی به عنوان شاهد استفاده گردید. نازل ها همگی از نوع بادبزنی موسوم به استاندارد و عبارتند از: tee jet 11002, tee ...
abstract in the present article, effective parameters of the buoyant jets have been evaluated in the stagnant ambient fluid. the jet parameters, geometry parameters and environmental parameters are investigated. using dimensional analysis, a set of dimensionless functions was obtained. to achieve the exact functions, a physical model was built in the hydraulic laboratory of shahid chamran unive...
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 ...
This article studies the flow structures and main patterns driving dynamics in one two planar synthetic jets. We perform numerical simulations at different Reynolds numbers (Re), for a similar forcing frequency, to model jet jets, which present movement in-phase (synchronous jets) out-of-phase (asynchronous jets). identify types of regimes as function number: (i) is symmetric (ii) symmetry brok...
Breaking bad news to the patients does not back to a long history and is a controversial issue between patients and physicians. Many physicians are reluctant to breaking bad news to patients and this is not desirable for most patients. For example, in Northern European countries and United States, most physicians usually break bad news to the patients, while in Southern and Eastern European cou...
Road traffic accidents are the leading cause of death in international travelers. With the growth of international travel, the number of visitors who rent a vehicle upon arrival at their destination by air or by sea is expected to increase. Jet lag is a well-recognized maladaptation to international travel across multiple time zones. Little is known about the possible influence of jet lag sympt...
