Approach
Hele-Shaw flow
- Flow between closely-spaced parallel plates
- Described by linear 2-D equation (Darcy’s law)
- 1000's of references
- Practical application - flame propagation in cylinder crevice volumes
Premixed-gas flames, PLUS propagating chemical fronts in aqueous solution
- d º Dr/r << 1 - No baroclinicity, Bousinnesq approximation valid
- DT 3 K - no change in transport properties
- Not affected by heat loss
- Large Schmidt # - front stays "thin” even at high Re
- Simpler chemistry than gaseous flames
-
