A Reynolds number is a dimensionless number used in fluid dynamics.
雷诺数是流体动力学中使用的一种无量纲数。
Engineers compare heat transfer performance using dimensionless numbers such as the Nusselt and Prandtl numbers, which help scale results from models to real systems.
工程师会用努塞尔数、普朗特数等无量纲数来比较传热性能,这些数有助于把模型实验结果推广到真实系统。
Osborne Reynolds 的论文 “An Experimental Investigation of the Circumstances which Determine whether the Motion of Water shall be Direct or Sinuous…”(1883)中围绕后来称为“雷诺数”的无量纲思想展开。
Rayleigh(J. W. Strutt)的 “On the Convection of Heat in a Fluid”(1916)等传热研究中大量使用无量纲形式与无量纲参数。
Frank M. White,《Fluid Mechanics》常系统介绍各类无量纲数及其物理意义。
Bird, Stewart & Lightfoot,《Transport Phenomena》用无量纲化与无量纲群贯穿动量/热量/质量传递分析。
Incropera 等,《Fundamentals of Heat and Mass Transfer》中广泛使用努塞尔数、普朗特数等无量纲数来关联实验与理论。
