Venturi aeration of bioreactors
… products. Some research has suggested that venturi aeration of bioreactors will reduce energy consumption by eliminating the need for air compression, while at the same time maintaining or improving oxygen transfer rates. On the other hand, there are findings that suggest venturi aeration …

Boredom's Metamorphosis: Robert Venturi and Saul Steinberg
… figures: the American-Italian architect Robert Venturi (b. 1925) and the Romanian-born American architect and artist Saul Steinberg (1914-1999). The topic of boredom in architecture, and specifically within this timeframe, has been largely ignored in architectural history, theory, and criticism …

Thinking, Seeing, Practicing Architecture: From The Smithsons To Scott Brown And Venturi
… to that of Denise Scott Brown and Robert Venturi to reveal a shared attitude toward “the real.” I argue that each couple utilized a mode of visual research that was inspired by the social sciences; each relied on straightforward photographic documentation to represent their findings; and …

Data Analysis of an Unsteady Cavitating Flow on a Venturi-type Profile
… data. The data acquisition is implemented in a Venturi-type test section. The approximate Reynolds number based upon the throat height is 10,000, and the approximate cavitation number is 1.95. The non-equilibrium cavitation model assumes that the phase production and destruction are correlated …

Increasing Isentropic Efficiency with Hydrostatic Head and Venturi Ejection in a Rankine Power Cycle
… hydrostatic head generated by elevation and venturi ejection for use by the condenser is developed along with the equations needed to predict the changes to the system. These equations were used to create software to predict efficiency as well as lay down the foundation for future …

Experimental analysis of an energy self sufficient ocean buoy utilizing a bi-directional turbine
An experimental analysis of a Venturi shrouded hydro turbine for wave energy conversion. The turbine is designed to meet the specific power requirements of a, Woods Hole Oceanographic Institute offshore monitoring buoy using a unique gumby hose mooring system. The buoy's mission is to monitor the …

Evaluation of exhaust flowrate measurement techniques for a mobile emissions monitoring system
… a hot film anemometer, a Pitot static tube, a venturi, and a vortex shedder.;The evaluation of the devices was broken down into two parts, the first part included cold bench testing and the second engine testing. The venturi was found to be the best flow device for a MEMS because of the …

Considerations for Contemporary Design and Land Use Within Existing Historical Context
… should ever be considered unimportant. As Robert Venturi said in his “Gentle Manifesto”, a designer should strive towards “messy vitality over obvious unity” (Venturi, 1966). Finding a simple design resolution is difficult if not impossible in a complex urban city layered with centuries of …

Bubble Size Effects in Coal Flotation and Phosphate Reverse Flotation using a Pico-nano Bubble Generator
… order to obtain an optimal designed cavitation venturi tube for pico-nano bubbles' generation, different designs of cavitation venturi tubes were fabricated and tested in this study. The test results showed that maximum volume of pico-nano bubbles, 65% to 75%, and minimum mean pico-nano bubble …

Dynamics of Lean Direct Injection Combustors
… Next, while varying the swirl number and the venturi geometry of the combustor, the evolution of the flow field will be characterized. An in-house innovation called the Direct Rotation Swirler (DRS) is built for this purpose. The DRS uses an active geometry to provide continuously variable …
