The invention provides a ship bow flow guide type bubble resistance reduction device and a resistance reduction method, and belongs to the field of ship energy-saving devices. The problems that an existing air inlet mode is used for generating bubbles, the efficiency is low, and the speed of discharging the bubbles out of the ship cannot be guaranteed to be stable are solved. The device comprises a gas production mechanism, a gas conduction mechanism, a gas release mechanism and two water flow guide mechanisms, the gas production mechanism is arranged at the bow position of a ship body, the gas release mechanism is arranged at the bottom of the ship bow, and the gas production mechanism and the gas conduction mechanism are arranged on the center line of the ship body. The two water flow guide mechanisms are symmetrically distributed on the left side and the right side of the ship bow, the gas production mechanism communicates with the gas conduction mechanism, the gas conduction mechanism communicates with the gas release mechanism, and the two water flow guide mechanisms communicate with the gas release mechanism and are symmetrically arranged on the left side and the right side of the gas release mechanism. The method is suitable for drag reduction in the ship running process.
