In order to study the action mechanism of compound solvent in magnetization modification,a magnetic field generator was established firstly.The corresponding iron core shapes,which are C-shape and E-shape,were selected to draw two magnetic field generator models.With the help of simulation software and corresponding electromagnetic numerical simulation,the magnetic field distribution characteristics under different current excitation and gap were studied.The 0.6T?0.8T required by magnetization is achieved.The simulation results show that under the same section size and surface current excitation,the C-shaped core has better electromagnetic sensitivity than the E-shaped core,and the magnetic induction at the gap increases obviously with the increase of the same surface current excitation.In the analysis of the influence of magnetic field on the flow of compound solvent,with the help of Multi physical field simulation software,using the particle tracking method to study the movement changes of particles,it is concluded that when the inlet velocity is0.04m/s,under the effect of 0.8T magnetic field intensity,the maximum and minimum flow velocity at the outlet is 0.001m/s larger than that without the effect of magnetic field;in the process of dilute material transfer In the process,when the inlet concentration is 1000mol/m3and the inlet velocity is 5×10-4m/s,the concentration after reaction is 0.002mol/m3lower than that without magnetic field under the effect of 0.8T magnetic field,which indicates that the kinetic energy of the system is increased and the reaction process of dilute material transfer is promoted under the effect of a certain magnetic field.Under the effect of external energy,the structure and properties of water molecules are analyzed,and the water molecule cluster box is established.By increasing the initial temperature,five indexes are selected to measure the changes of water molecules'dynamic simulation.It is concluded that the hydrogen bond between water molecules is extended under the effect of external energy.As a weak interaction between water molecules,the hydrogen bond is affected by the lengthening or breaking of hydrogen bond At the same time,the probability distribution of the bond length and the bond angle of the oxygen hydrogen bond in the water molecule changes under the effect of the external energy,and the probability distribution of the water molecule increases when the bond length increases to 0.98(?)and the bond angle decreases to 99°.
