Numerical Modeling of Cyclone Machine for Cleaning Gas Generator Gases

Abstract

Analysis of contemporary cyclone gas purification apparatus was carried out in this article Calculation of the characteristics of the counterflow cyclone in application of pressurization system of the LV fuel tanks with gas pressure accumulator has been executed. 3D-model of the counter-flow cyclone was built. Numerical modeling of soot-cleaning process in countercurrent cyclone has been performed using ANSYS Fluent.

Optimization of Geometric Parameters of the Cyclone Apparatus Based on its Numerical Modeling

“…From the result of the research [5], the number of particles which pass through the apparatus per 200 seconds is equal to 629677. 78,3% of them (492893) were delivered to a soot-catching storage, 21,3% (134209) of them were still inside the flow channel and 0,4% (2575) were not separated from the flow and left the cyclone with cleaned gas.…”

“…For this purpose, a numerical modeling of a different configuration of cyclones was carried out in the ANSYS Fluent software. [3,4] The opposite-flow cyclone, presented in [5], was selected as a prototype.…”

Investigation of the Temperature Effect on the Sensitivity of Thermal Conductivity Detector

“…Another factor affecting the results of the chromatographic analysis is temperature fields distribution in the gas chromatograph detector. Output channels configuration in the gas chromatograph detector should provide uniform temperature fields distribution at constant gas-flow rate [7].…”

Calculation Methodology of Power Plant Universal Cycle Using Low-grade Heat of Refrigerant

“…For this purpose it is sufficient to investigate the generalized polytropic cycle (Figure 2), which is limited by the following assumptions: 1) processes are reversible; 2) the specific heat, and hence the polytropic indices are constant values; 3) working body -ideal gas; 4) heat supply is carried out during II, removal -during IV; 5) heat transfer in the process I is absent, although the process is considered as a polytropic (a consequence of the IPOA specificity, in which energy components are supplied either liquid, or in a precompressed state); 6) Process III is considered to be adiabatic [7]. The equation ߟ ௧ .о of polytropic cycle should include the maximum-to-minimum cycle temperature ratio ܶ ଷ /ܶ ଵ cycle and the pressure at point 4 -p 4 .…”
