by means of which the flow Profile can be modelled with or without consideration of buoyangcy.Tests show
that with consideration of buoyangcy the recirculation zone in burner flame will be reduced
the axial valocity at the rear wall will be attenuated more quickly and the the whole flow profile in furnace varies in. comparison with the case without consideration of buoyangcy.Therefore
it is necessary to take into consideration the buoysngcy in modelling the process in combustion chamber in hot state.
