得到了粘弹性流体在拉伸表面上磁流体流动的热质传递的精确解。的解决方案的传热和传质特性进行了数值评估不同的参数，如修改后的普朗特数P*r，磁参数M，表面温度指数S，和修改后的施密特数S*c。结果表明，磁场的存在使流体温度和质量浓度均升高，而壁面传质系数随修正施密特数的减小而减小。本文所作的分析比以往任何一项研究都更具有普遍性。
Exact solutions are obtained for the heat and mass transfer in a hydromagnetic flow of the visco-elastic fluid over a stretching surface. The solutions for the heat and mass transfer characteristics are evaluated numerically for different parameters, such as the modified Prandtl number P*r, the magnetic parameter M, the surface temperature index S, and the modified Schmidt number S*c. It is observed that both the fluid temperature and the mass concentration increase due to the existence of the magnetic field, and the mass transfer coefficient at the wall decreases as the modified Schmidt number decreases. The analysis presented in this paper is more general than any previous investigation.
