Gas Dynamics in a Counterflow Cyclone with Conical Nozzles on the Exhaust Pipe
Countercurrent cyclones have been quite widely applied in various industries [1-12]. In this paper, on the example of classical construction of countercurrent cyclone considers the impact of the conical nozzle on the exhaust pipe to the gas-dynamic picture and efficiency dedusting.
Synchrotron X-ray diffraction study for solid CO2 at 40?100 GPa and around 2,000 K has shown that the diffraction pattern of the high pressure phase CO2-V is consistently interpreted in terms of a tetragonal uni_t cell (Z = 4, a = 3.584 ?, c = 5.908 ? at 50GPa). A ?-cristobalite structure (space group I2d) gives a good account of our data qualitatively. Isothermal molar volume (300K) of the CO2-V in the present study is smaller than that indexed as a tridymite structure proposed by previous studies at any pressures.
