Study of Gas Dynamics in the Heat-accumulation Stoves
The paper aims to clarify some aspects of the gases hydro-dynamics within the twisted conduct of heat accumulation stoves (ceramic-refractory stoves) downstream the combustion chamber. Both Comsol laminar and k-e turbulent models have been used in case of straight and curved pipes with circular, square and rectangular cross-sections, at different Reynolds numbers, in case of smooth wall (Comsol turbulent models doesn’t describe rough surfaces).
While Comsol models seam properly simulate fluxes at low Reynolds numbers (Navier-Stokes model) and at high Reynolds numbers (k-e model), in the transition zone, between laminar and turbulent motion, the solution of the k-e model at low Reynolds numbers appears distant from the literature experimental results and strongly dependent on the computing grid.
