cauchy number calculator the cauchy number (ca) is a dimensionless number associated with compressible flow in fluid mechanics. it is named after the french mathematician augustin-louis cauchy. when the impact of compressibility is large, elastic force also needs to be considered when considering dynamic similar inertia forces. the cauchy number is the ratio of the fluid's inertial force to its compressive force (elastic force). the calculation formula is shown in the figure above, where: ρ - fluid density (si unit: kg/m3); v - local fluid velocity (si unit: m/s); k - bulk modulus (si unit: pa) .
