Osborne Reynolds' observations of types of water flow in pipes.

Summary[edit]

Description
English: Water flow observed in a pipe, as drawn by Osborne Reynolds in his best-known experiment on fluid dynamics in pipes. Water flows from left to right in the transparent tube, and dye (represented in black) flows in the middle. The nature of the flow (turbulent, laminar) can be observed easily. These drawings were published in Reynolds’ influential 1883 paper "An experimental investigation of the circumstances which determine whether the motion of water in parallel channels shall be direct or sinuous and of the law of resistance in parallel channels".

L’eau s’écoule de gauche à droite dans le tuyau transparent, et de la teinture s’écoule au centre. La nature de l’écoulement (turbulent, laminaire) peut être observée facilement. Ces dessins ont été publiés dans la publication influente de Reynolds nommée "An experimental investigation of the circumstances which determine whether the motion of water in parallel channels shall be direct or sinuous and of the law of resistance in parallel channels" en 1883.
