| Abstract: | The heat transfer characteristics of an electroconducting fluid under the magnetic field and the acoustic field in a tube are studied in the paper. The relations between the effective enhanced thermal diffusivity K ef and the dimensionless angular frequency and the Hartmann number Ha are obtained. The conclusions show that the magnetic field and the oscillation can enhance the heat transport of the electroconducting fluid. |

| Keywords: | electroconducting fluid heat transfer enhancement oscillation magnetic field |
