Small-diameter-wire grids were used as turbulence generators in a l/2-inch nozzle burner to produce laminar-like propane-air flames subject, to flow disturbances of a small scale compared to the reaction-zone thickness.nBoth laminar-like and brush-like flames were obtained. Some laminar like flames were obtained (for grid-disturbed flow) which had a slightly higher burning velocity than "true" laminar flames (no grid used). This finding agrees with Damkohler's theory on the effects of small-scale turbulence.
