Flow entrainment

WebVenturi mask. The venturi mask, also known as an air-entrainment mask, is a medical device to deliver a known oxygen concentration to patients on controlled oxygen therapy. [1] [2] The mask was invented by Moran Campbell at McMaster University Medical School as a replacement for intermittent oxygen treatment. Dr. Entrainment is the transport of fluid across an interface between two bodies of fluid by a shear-induced turbulent flux. Entrainment is important in turbulent jets, plumes, and gravity currents and is a topic of current research. See more The entrainment hypothesis was first used as a model for flow in plumes by G. I. Taylor. He was studying the use of oil drum fires to clear fog from airplane runways during World War II. It became a … See more Eductors or eductor-jet pumps make use of entrainment.

WebTypical values for the entrainment coefficient are of about 0.08 for vertical jets and 0.12 for vertical, buoyant plumes whilst for bent-over plumes, the entrainment coefficient is about 0.6. Conservation equations for mass (including entrainment), and momentum and buoyancy fluxes are sufficient for a complete description of the flow in many cases.

WebDec 15, 2024 · Minimum flow rates will also play a major role when managing air entrainment issues. The higher the air entrainment percentage the more flow that will be required to push or sweep the air bubbles pass the impeller eye (see Figure 1). So, operating the pump to the left side of the curve can lead to air binding blockages. Air … WebThe flow entered the entrainment adapter section as a jet since the fuel flow was constricted to an orifice area of 3.14 × 10-8 m 2 before expanding and entering the four microchannels. Approximately 30-seconds after fuel was introduced into the system, the power supply was turned off after achieving autothermal combustion.
