Abstract
The excitation and propagation of exothermic reaction waves in a closed channel filled with gaseous oxygen at initial pressures of 0.1 to 2 MPa was studied. The waves were excited by a hot nichrome coil coated with a small amount of VM-4 vacuum oil or melted fat. The wave parameters and initial pressures at which flame propagation occurs in the channel were determined.
