noun[mass noun] Physics
Laminar or streamline flow of an incompressible viscous fluid, especially through a long, narrow cylinder.
- We have used shear-flow drag forces instead of Poiseuille flow (which actually exists within the parallel-plate flow chamber) to compare predictions with experiments.
- The difference between their situation and the one presented here is that the particles in that work are located at the centerline of Poiseuille flow, and thus the drag force is well defined by the Stokes drag on a sphere.
1940s: named after Jean L. M. Poiseuille (1799–1869), French physician.
