AI 中文摘要
我们通过直接数值模拟研究对流的维度对流动特性的影响，综合1维、2维、3维、4维的结果，揭示了若干通用原理，重点探讨两个实际方面：一是流动达到稳态所需的瞬态时间，二是对所谓“终极态”可能产生的影响。
英文摘要
We study by means of direct numerical simulations the influence of the dimensionality of convection on flow properties. We call attention to a few general principles from considering in totality the results from one dimension, two dimensions, three dimensions and four dimensions. In particular, we explore two practical aspects: (1) the transient time, or the amount of time it takes for the flow to reach the steady state; and (2) possible implications for the so-called ultimate state.
