THREE-DIMENSIONAL MATHEMATICAL SIMULATION OF A GAS-FIRED FURNACE WITH A SWIRLING FLOW
|
| |
|
Summary :
|
|
ABSTRACT. THE GAS COMBUSTION TURBULENT SWIRLING FLOW IN FURNACES PRESENTS A COMPLEX FLUID-DYNAMIC BEHAVIOR WITH PHENOMENA SUCH AS REVERSION FLOW, RECIRCULATION ZONES, VORTEX PRESERVATION AND HIGH SENSITIVITY TO BURNER DESIGN. IN THIS WORK WE PRESENT A THREE-DIMENSIONAL FLOW MODELLING AND THE NUMERICAL SOLUTIONS OBTAINED BY THE FINITE-VOLUME WITH THE BODY-FITTED METHODS FOR GRID GENERATION AND THE MULTI-BLOCK TECHNIQUE, THE K-"E" TURBULENCE MODEL AND THE MIXED-IS-BURNT COMBUSTION MODEL USING THE CFX-F3D COMPUTATIONAL FLUID-DYNAMICS CODE. THE GEOMETRICAL MODEL SHOWS A SATISFACTORY CAPABILITY TO PREDICTING ALL FLUID DYNAMICS BEHAVIOR, AND THE VARIABLE FIELDS ARE OBSERVED BY THE SCIENTIFIC VISUALIZATION OF THE FLOWS.
KEYWORDS: FURNACE, COMPUTATIONAL FLUID DYNAMICS, CFX.
