Hi,
I'm working on a premix burner of a boiler: it should distribute the mix air+gas from the fan the to the heat exchanger (after have gone through a certain circuit). Since there's a metal fiber (1 mm thick), I prefer use porous model (to avoid a mesh too heavy). I think that in this case I can use Porous jump rather than Porous zone because the burner is very thin (even if a bit curved). Am I right? Above all I need some advice to define Inertial & Viscous Resistances: after experiments I got Viscous Resistance closed to zero: can i put "0" where Fluent asks me the permeability? and C2 about 500000 is realistic? (the flow is turbulent) Please help me  (excuse me for my horrible english) Last edited by Bionico; October 14, 2011 at 05:17. |
