Abstract:-The FSAE guidelines state that it is mandatory for each and every car participating in the said event to have a single circular 20mm restrictor in the intake system. All the air flowing to the engine must pass through this restrictor. Conventionally, a Venturi Nozzle is used as a restrictor. In our research, we have proposed two Nozzles: De-Laval Nozzle and Bell Nozzle as an alternati...

in this study, a numerical simulation using the cfd software, fluent, has been conducted to examine the effect of various shapes of the venturi component sections in order to find the optimum venturi specifications to increase the egr rate with minimum pressure loss at the part load operation range. the cfd results reveal that the venturi should be precisely optimized to introduce the required ...

Monitoring the flow rate out of the well is critical for good control of the downhole pressure in drilling operations. In this feasibility study, we explore the possibility of using a Venturi flume to provide a cost-effective measurement of the flow rate, with improved accuracy compared to conventional methods. A Venturi flume has been simulated both using CFD and a simplified 1D model. By prop...

Sir,—Intermittent jets of oxygen may be used to ventilate patients undergoing microlaryngoscopy with a Venturi injector or by flushing oxygen directly through a small-bore endotracheal tube as we have used in 10 adult patients (table I). The patients were premedicated with pethidine 75 mg and atropine 0.6 mg and anaesthesia was induced with propanidid 250-500 mg followed by suxamethonium 100 mg...

OBJECTIVE Over the past 20 years, jet ventilation techniques have been developed to enable safe and controlled microlaryngoscopy and the accurate treatment of laryngeal pathology. This study examined how advances in jet ventilation tube design have facilitated safe endolaryngeal surgery. STUDY DESIGN The study documented the development and use of the Jockjet subglottic jet ventilation tube s...
