Mixing gases at supersonic velocity

Claim 1

METHOD OF MIXING AT LEAST TWO CHEMICALLY REACTIVE GAS STREAMS WHICH COMPRISES THE STEPS OF SUPPLYING SEPARATE STREAMS OF EACH OF SAID GASES AT SUBSONIC VELOCITY AND AT ELEVATED TEMPERATURES SUCH THAT THEIR AVERAGE TEMPERATURE IS ABOVE REACTION TEMPERATURE, SUBDIVIDING EACH OF SAID STREAMS INTO A GROUP OF SMALLER, NARROW STREAMS, ACCELERATING THE GAS OF EACH SAID NARROW STREAMS TO SUPERSONIC VELOCITY SUFFICIENT TO THEREBY COOL THE GASES TO BELOW REACTION TEMPERATURE, DISCHARGING THE RESULTANT, COOLED SUPERSONIC STREAMS IN A SUBSTANTIALLY COMMON DIRECTION IN CLOSELY INTERSPERSED RELATION INTO ONE END OF AN ELONGATED MIXING ZONE, FLOWING SAID STREAMS THROUGH SAID MIXING ZONE CONTINUOUSLY AT SAID SUPERSONIC VELOCITY AND WITHOUT CHEMICAL REACTION BETWEEN THE GASES THEREOF FOR A DISTANCE AT LEAST TWENTY TIMES THE MAXIMUM WIDTH OF THE WIDEST OF SAID NARROW STREAMS AT THE UPSTREAM ENDS THEREOF AND EFFECTING LATERAL MIXING BETWEEN SAID STREAMS OF DIFFERENT GROUPS DURING SAID FLOW AND THEREAFTER FLOWING THE RESULTING MIXTURE PAST A PARTIAL FLOW OBSTRUCTION IN THE PATH OF THE MIXTURE AND THEREBY CREATING A STRONG SHOCK WAVE AND EFFECTING A RISE IN THE TEMPERATURE OF THE MIXTURE.
