Characteristic length 意味

WebThe flow is in the volume between the inside and outside pipe. Based on equation (1) the hydraulic diameter of a circular duct or tube with an inside duct or tube can be expressed as. dh = 4 (π ro2 - π ri2) / (2 π ro + 2 π ri) = 2 (ro - ri) (3) … WebWe can compute Reynolds number to determine if the flow is laminar or turbulent, therfore we need a characteristic length; for example, In the case of external flow around an airfoil, we can consider $ L =c$ the chord of the airfoil. For internal flows, the characteristic length is the hydraulic diameter. My question is: in the case of a cigarette smoke, what is the …
