ignition problem
Hi to all,
Im trying to solve the hydrogen-oxygen flame acceleration transient 2D task using one part closed tube with obstacles. As the open part of the tube I use pressure outlet set up. As a ignition I use a ignition wall ( 4 little walls near the closed part of the geometry) with 2000 K, heat transfer coeff set to 10 - for the convection. Firstly, I run the task as a steady-state, and it seem to be no combustion at all. No pressure change, no temperature change, no flux. By the iterating, the temperature increased to about 2300 K (in a distant point) and then drop to default set up. Am I right, when I thing that steady-state analysis solve the problem in t -> infinity? But also no change occured with unsteady analysis. Where did I go wrong?.. Thank you in advance gentlemen. |
No one has a experience with hot surface ignition?
