System Fabrication:Fuel Proof Resin• Possible material for velocity stacks:

www.Epoxy.com - Product #670Vinyl-Ester ResinFuel-Proof 6-months testing300°-400° Temperature

System Fabrication:Velocity Stacks • Machined aluminum velocity stack mold• Dimensions

– 1.35 inch diameter– 0.5 inch bell– 7.5 inch long

Velocity Stack Design:Loss Coefficient for Bell Curve• Rounded Entrance• To minimize K, loss coefficient at the bell

entrance– R/D=0.5/1.35=0.371– According to table in Applied Fluid Dynamics

Handbook by Blevins, K is between 0.01-0.03

Plenum Modeling:Gambit Meshing
