In this article we derive expressions for Casimir-like pressures induced by nonequilibrium concentration fluctuations in liquid mixtures. The results are then applied to liquid mixtures in which the concentration gradient results from a temperature gradient through the Soret effect. A comparison is made between the pressures induced by nonequilibrium concentration fluctuations in liquid mixtures and those induced by nonequilibrium temperature fluctuations in one-component fluids. Some suggestions for experimental verification procedures are also presented.
本文推导出了由液体混合物中非平衡浓度涨落引起的类 Casimir 压力的表达式。然后,将这些结果应用于由于 Soret 效应导致温度梯度而引起浓度梯度的液体混合物中。比较了由液体混合物中非平衡浓度涨落引起的压力和由单组分流体中非平衡温度涨落引起的压力。还提出了一些实验验证程序的建议。
