Combustion and Flame
Structure and behavior of water-laden CH4/air counterflow diffusion flames
Rose Padilla and their team/collaborators report on experiments where they measure methane/air combustion flames mixed with water. The goal is to understand the effects of having water on the fuel side where in real world situations the water can be introduced arbitrarily or occurs naturally as in methane hydrates.
The researchers measure the PLIF of OH radicals to characterize the flame reaction zone using a PI-MAX4 ICCD camera. The same camera is used for chemiluminescence CH molecules as well.
