An example system includes a combustion chamber including at least one inlet and at least one outlet, and at least one reflective surface to direct shock waves in a pattern that meets at a midline nodal point. The example system also includes an ignition source to generate high enthalpy colliding and reverberating shock pressure waves and detonation gasses for dynamic pressurization. An example method for using high enthalpy colliding and/or reverberating shock pressure waves for chemical and material processing. The example method includes providing a combustion chamber including at least one inlet and at least one outlet, and at least one reflective surface to direct shock waves in a pattern that meets at a midline nodal point. The example method also includes colliding reflected or opposing combustion-induced or detonation-induced wave fronts within the combustion chamber.
