GAS FLOW WALL FACE FRICTION RESISTANCE REDUCTION DEVICE, ITS APPLICATION METHOD AND GAS FLOW WALL FACE FRICTION RESISTANCE REDUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a gas flow wall face friction resistance reduction device to reduce gas flow wall face friction resistance and a reduction method of the gas flow wall face friction resistance to provide a device which can reduce the air flow wall face friction resistance simply, its application method and the reduction method of the gas flow wall face friction resistance.;SOLUTION: The wall face friction resistance reduction device comprises a magnetic attraction generating means for applying a magnetic attraction force to a gas flow in contact with the wall face toward a wall face vertically to the wall face in the vicinity of the wall face in contact with the gas flow including oxygen gas or the gas flow including oxygen gas to reduce the wall face friction resistance.;COPYRIGHT: (C)2007,JPO&INPIT
