HORIZONTAL HELE-SHOW INSTALLATION FOR RESEARCHING LAMINAR CELLULAR FLAMES

An experimental setup for studying the flame propagation of methane and propane-air mixtures with hydrogen in the Hele-Shaw channel is described. The setup was assembled in laboratory conditions and is a channel of two parallel glass plates with partitions installed between them, which form a trapezoidal flat diffuser. Visualization of the flame front between the transparent plates of the channel was carried out, which made it possible to detect changes in the shape and structure of the flame front due to hydrodynamic and heat diffusion factors.
