Mixing with jets in cross-flow
Web18 sep. 2014 · The second stage reaction was modeled using two different configurations: The worst case scenario being the combustion of the mixture in the jet without any interaction with the hot cross flow, and the most favorable case being the jet and the cross flows perfectly mixed and then burned. Web1 jan. 1993 · The experiments and empirical model for the mixing of a single row of jets from round holes were extended to include several variations typical of gas turbine combustors, namely variable temperature mainstream, flow area convergence, noncircular orifices, and double and opposed rows of jets, both inline and staggered.

WebThese shockwaves of opposite families starting at the nozzle trailing edge, cross each other at the jet axis and travel to the jet boundary and are reflected as expansion waves. These shock and expansion waves cause a periodic shock-cell structure in the jet flow field. Figure 1.1 schematically shows the shock-cell structure in an over expanded ... Web24 nov. 2008 · We use direct numerical simulation to study the mixing behaviour of pulsed jets in crossflow. The pulse is a square wave and the simulations consider several jet velocity ratios and pulse conditions.
WebThe ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more jet thrust relative to fan thrust are known as low-bypass turbofans , conversely those that have … Web20 jul. 2010 · Modulated liquid jets injected into subsonic cross-flows are empirically studied by using a mechanical liquid jet modulation apparatus. Experimental investigations were conducted using water over a range of cross-flow velocities from 5 m/s to 143 m/s and with modulated liquid jet frequencies from 35.7 Hz to 166.2 Hz and so on.
Web15 jun. 2011 · Jets in cross flow (JICF) are used in several engineering applications related to heat and mass transfer. Single, twin and multiple jets are introduced within the cross flow according to the aim of the handled application. Twin and multiple jet configurations are found in combustor wall cooling, cooling of gas turbine blades, etc. Webparty 196 views, 4 likes, 1 loves, 7 comments, 1 shares, Facebook Watch Videos from Hardy Street Baptist Church: Sunday Morning Worship Celebration
