A model of a submerged angular cavitation nozzle is established, which consists contraction part, parallel middle and expansion part. Based on the CFD technique, numerical simulation flow field carried out, in multiphase mixture model, renormalization group (RNG) k-ε turbulence are applied. Considering influence density cavitation, effects inlet outlet part velocity vapor volume fraction studie...

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...

Abstract Plasma based treatments are found to be effective in water cleansing. For this purpose, we employed a plasma jet that is extracted at the exit of flexible plastic tube remotely from its main source. This generated using gas mixture argon and oxygen for sake producing reactive species solution when submerged safely under perform treatment suspension volume. The treated samples consist d...

Metarhizium anisopliae var. acridum (IMI 330189) can produce at least three spore types in vitro ; blastospores, submerged conidia, and aerial conidia, as defined by culturing conditions, sporogenesis, and spore morphology. This study compares morphological characteristics (dimensions and cell wall structure), chemical properties of cell wall surfaces (charge, hydrophobicity, and lectin binding...

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 ...

To investigate the temperature sensitivity of low-Ca2+-induced nonsynaptic and low-Mg2+-induced synaptic ictogenesis under submerged and interface conditions, we compared changes of extracellular field potential and extracellular potassium concentration at room temperature (23 +/- 1 degrees C; mean +/- SD) and at 35 +/- 1 degrees C in hippocampal-entorhinal cortex slices. The induction of spont...

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...

in this research, the frequency of the jet streams associated with extreme and pervasive precipitation has been analyzed using environmental to circulation approach. based on the 99th percentile index, 109 days of the extreme and pervasive precipitation was selected from the irimo data base ( including 33 synoptic, climatic and rain gage stations during 15992 days from farvardin, 1st, 1340 to d...
