论文摘要
我们关注的是在扩散存在下的流动增强的被动标量混合。在假设速度梯度适当整合的假设下，我们就增强耗散的指数速率提供了上限。最近的结构表明我们的结果的最佳性。
We are concerned with flow enhanced mixing of passive scalars in the presence of diffusion. Under the assumption that the velocity gradient is suitably integrable, we provide upper bounds on the exponential rates of enhanced dissipation. Recent constructions indicate the optimality of our results.
