Power transportation of high intensity torch plasma arc in a function of high-speed cross-wind

Summary form only given, as follows. The torch plasma parameters were studied in detail by applying the high-speed cross-wind The transformation behaviors, plasma voltage, quantity of heat being received by cooling water inside the anode were examined The plasma length stretched gradually as the cross-wind velocity became higher. The higher the current of the torch plasma became, the higher the break velocity of the cross-wind became The higher plasma gas flow rate of the torch plasma made changing rate of the plasma voltage lower at higher cross-wind velocity. When the cross-wind velocity was under 37 m/s, the plasma voltage did not have a difference so much for each plasma gas flow rate, but when it was over 37 m/s, the plasma, voltage increased dramatically and the higher plasma gas flow rate of the torch plasma had higher maximum plasma voltage. The increase of plasma power by cross-wind velocity becomes milder with increasing current, and the substantial change in plasma power that is dependent upon cross-wind velocity is considered due to the energy loss by cross-wind Exposing the plasma to the cross-wind little by little, starting from no wind, initially the Q/sub anode/, the quantity of heat received by cooling water inside the anode, had a gentle decrease, but as the cross-wind velocity increased over the critical value of V/sub cc/, cross-wind speed, it shifted to a dramatic decrease. The rate of reduction of Q/sub anode/ for the cross-wind velocity becomes slightly lower, so that current becomes higher. The difference of Q/sub anode/ for each plasma gas flow rate is smaller than Q/sub anode/ for each current. The heat received by cooling water inside the anode under cross-wind highly depends on current. And after the plasma voltage increases dramatically because of increase of cross-wind, the changing rate of the heat received by cooling water inside the anode depends on plasma gas flow rate.
