Definition of Peclet number in English: Peclet number(also Péclet number) noun ˈpɛkleɪ ˌnʌmbə Physics A dimensionless parameter used in calculations of heat transfer between a moving fluid and a solid body, representing the ratio of the convected to the conducted heat and equal to the product of the Reynolds number and the Prandtl number, viz. Dvcp/k, where D is a characteristic length of the body, v is the speed of the fluid past it, cp is the heat capacity of unit volume of the fluid at constant pressure, and k is its thermal conductivity. Abbreviated Pe.
Origin1930s. From the name of J. C. E. Péclet, French physicist + number.
