永磁场对气体中分子传质过程的影响

Influence of Permanent Magnetic Field on the Molecular Mass-Transfer Process in Gas Phase

在不同磁感应强度的磁场中,研究了磁场对气体中分子传质过程的影响。研究结果表明,磁场对水、甲醇、乙醇、甲酸及乙酸在空气中的分子传质过程具有正效应,即在磁场中的扩散系数增大。定量计算表明,其扩散系数提高4%～7%。磁场对苯、甲苯、丙酮及甲基乙基酮在空气中的分子传质过程基本无影响。对磁场影响气体中分子传质过程的机理进行了探讨。

In the magnetic field which has different intensity of magnetization, the influence of permanent magnetic field on the molecular mass-transfer process in gas phase was investigated. The results indicate that magnetic field have positive effect on the molecular mass-transfer process of water,methanol,ethanol,formic acid and acetic acid in the air,viz diffusivity increase in the magnetic field. The quantitative account shows that the diffusivity increases 4%—7%, magnetic field have no effect on the molecular mass-transfer process of benzene,toluene,acetone and methyl ethyl ketone in the air. Through analyzing on experimental result, the mechanism of permanent magnetic field on the molecular mass-transfer process in gas phase was discussed.
