Abstract:
Apparatus comprising:a source of feedstock gas,a rigid shell defining an enclosed interior volume,first means for conducting a first quantity of said feedstock gas from said source of feedstock gas to a first specific region within said enclosed volume within said rigid shell,a quantity of inert gas located within said rigid shell,whereina resonant pressure wave exists within said enclosed volume, said resonant pressure wave being identified with oscillatory motions of at least a portion of said inert gas at an oscillation frequency,a velocity node exists within said first specific region,said velocity node has pressure wave pressure range which is greater than the pressure wave pressure range at the interior surface of said rigid shell,said first means for conducting said first quantity of said feedstock gas from said source of feedstock gas to said specific region within said enclosed volume within said rigid shell permits said oscillatory motions of at least a portion of said inert gas which said oscillatory motions are radially oriented with respect to said first specific region.
