Centrally staged swirl combustion can effectively reduce NOx emission. However, the complex field is susceptible to producing large-scale coherent structures, such as precessing vortex core and central (CVC). This study mainly investigates effect of CVC on flow flame in a centrally spray combustor at elevated temperature pressure using 10 kHz high-speed CH* chemiluminescence (CL), 20 particle image velocimetry, CH2O planar laser-induced fluorescence (PLIF). For pilot flame, both CL PLIF are...
GitHub is successful open source software platform which attract many developers. In GitHub, developers are allowed to fork repositories and copy without asking for permission, make contribution projects much easier than it has ever been. It significant predict the number of forks projects. The prediction can help recommend popular projects, guide find likely succeed worthy their contribution.
Control of combustion instability for a realistic gas-turbine combustor is challenging. This work aims to establish an efficient numerical framework optimization improve the stability bluff-body combustor. Large eddy simulations spray process are conducted, and experimental measurements used evaluate accuracy baseline case. The air preheating temperature, Sauter mean diameter fuel droplets, location liquid injection regarded as input variables. root square pressure amplitude objective....
This work investigates the response of a conical premixed flame to dual-frequency excitation, based on integrated CH* signal collected from photomultiplier tube (PMT), upstream velocity disturbance measured by hotwire, and chemiluminescence captured high-speed imaging. The results show that, in addition excitation frequencies, notable can also be observed at difference frequency, where corresponding fluctuation is relatively small. result means contributes little response. Such interacted...
