A method/operation of suppressing detonation propagation in a first direction and promoting detonation propagation in a second direction in a gaseous mixture flow channel, having a sawtooth geometry, wherein the gaseous mixture flow channel is a detonation diode, the method comprising:
- inserting the detonation diode in the gaseous mixture flow channel, using a plurality of couplings, wherein the detonation diode includes a plurality of angled walls and a plurality of wedges in the sawtooth geometry formed as a series of pockets inside of the detonation diode;
- collecting and transmitting a gaseous mixture flow through an opening of a first end of the detonation diode, wherein the first end of the detonation diode is facing a plurality of sharp tips of the plurality of wedges, inside of the detonation diode, forming the sawtooth geometry;
- igniting, in an initial ignition, the gaseous mixture flow entering the detonation diode, causing a detonation front traveling through the detonation diode from an anterior end toward a posterior end of the detonation diode in a direction away from the initial ignition;
- weakening the detonation front by causing diffraction of the detonation front in the plurality of angled walls and the plurality of wedges in the sawtooth geometry formed as the series of pockets,
- wherein upon reaching a first tip of the plurality of sharp tips of a first wedge in the sawtooth geometry, a first upper part of the detonation front weakens in a first pocket of the series of pockets to a point where decoupling a flame of the detonation front from a shock of the detonation front occurs, as the detonation front travels through the detonation diode from the anterior end toward the posterior end of the detonation diode in the direction away from the initial ignition,
- wherein a first lower part of the detonation front continues to propagate reaching a second tip of a second wedge in the sawtooth geometry, a second upper part of the detonation front weakens in a second pocket of the series of pockets to a point where further decoupling of the flame of the detonation front from the shock of the detonation front occurs, as the detonation front travels through the detonation diode from the anterior end toward the posterior end of the detonation diode in the direction away from the initial ignition, and
- wherein a second lower part of the detonation front continues to propagate reaching a third tip of a third wedge in the sawtooth geometry, a third upper part of the detonation front weakens in a third pocket of the series of pockets to a point where complete decoupling of the flame of the detonation front from the shock of the detonation front occurs, quenching any remaining igniting of the gaseous mixture flow and preventing further detonation from traveling through the detonation diode from the anterior end toward the posterior end of the detonation diode in a direction away from the initial ignition;
- and wherein preventing further detonation from traveling through the detonation diode prevents detonation of the gaseous mixture in the gaseous mixture flow channel from causing catastrophic damage to human, structural and mechanical assets proximate to the gaseous mixture flow channel;
- and
- propagating, in the detonation diode, full detonation of the gaseous mixture flow in a direction opposite of the direction of suppressed detonation by:
- reflecting shocks of the detonation front from a plurality of oblique walls of the plurality of pockets inside of the detonation diode forming the sawtooth geometry and creating a plurality of transverse waves in the detonation front, and
- reigniting the detonation front by the plurality of transverse waves created from reflecting shocks of the detonation front from the plurality of oblique walls of the plurality of pockets, wherein the detonation diode is free of obstruction restricting the gaseous mixture flow in the gaseous mixture flow channel, and wherein the direction opposite of the direction of suppressed detonation is a constructed section of the gaseous mixture flow channel one of accepting and using full detonation of the detonation front free of catastrophic damage in a detonation reception chamber.
