Based on the related theorem equations and physical and chemical experimental data of fluid mechanics, thermodynamics and physical chemistry, the equations of motion, dissolution and stress of oxygen-boosting bubbles in water are established by means of numerical calculation. , The bubble radius of oxygen bubble which can be completely dissolved under different conditions is optimized, and the bubble size of oxygen gas is obtained when the water depth is less than or equal to 2m and the bubble radius is 0 1 ~ 0 5mm The relationship between the change of oxygen concentration, the rising distance and the dissolution rate was analyzed. The variation rule of oxygen bubble size, mass and movement in water was analyzed. The application of the calculation results was determined. The size of the bubble to provide a basis.
