单词	Prandtl number
释义	Prandtl number Chemical Engineering A dimensionless number, Pr, representing the ratio of the momentum of diffusivity to thermal diffusivity in fluid convection: $\Pr = \frac{c_{p} μ}{k} = \frac{P e}{Re}$ where c_p is the specific heat, µ is the viscosity, and k is the thermal conduction, Pe is the Péclet number, and Re is the Reynolds number. It is named after German scientist Ludwig Prandtl (1875–1953). Geology and Earth Sciences A dimensionless number, formulated by the German mathematician and aerodynamicist Ludwig Prandtl (1875–1953), that describes the ratio of kinematic viscosity to thermal diffusivity. The Prandtl number (Pr) is equal to v/α‎, where v is kinematic viscosity and α‎ is thermal diffusivity, both in units of m²/s.
