 Jean Claude Eugène Péclet

Jean Claude Eugène Péclet (1793–1857) was a French physicist and engineer known for his work in the fields of thermodynamics and heat conduction. Péclet is most notable for formulating the Péclet number, a dimensionless number that describes the relative importance of advection and diffusion in fluid flow. This concept is widely used in various fields, including engineering, physics, and environmental science, to analyze transport phenomena.
