Cauchy Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Cauchy number, abbreviated as Ca, a dimensionless number, is the ratio of inertial force to compressibility force in a flow.  When the compressibility is important the elastic forces must be considered along with inertial forces.


Cauchy Number formulas

\(\large{ Ca =  \frac{v^2 \;  \rho  }{ B }      }\)   
\(\large{ Ca =  \frac{v^2 \;  \rho  }{ B }      }\)  


\(\large{ Ca  }\) = Cauchy number

\(\large{ B }\) = bulk modulus elasticity

\(\large{ \rho  }\)  (Greek symbol rho) = density

\(\large{ v  }\) = velocity of flow
