Characteristic Length

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Characteristic length, abbreviated as \(l_c\), is the scale of a physical system.  The length is used in 2D and 3D systems for Fluid Dynamics and Thermodynamics defining the parameter of the system.

Examples of:

Characteristic Length Formula

\(\large{ l_c = \frac{ V } { A }  }\)         

Where:

\(\large{ l_c }\) = characteristic length

\(\large{ A }\) = object surface area

\(\large{ V }\) = object volume
