Entry from British & World English dictionary
The variation in velocity along a line at right angles to the general direction of flow.
- The parabolic velocity profile will generate a substantial distribution in residence time across w.
- The pressure-driven velocity profile in the duct-shaped device influences diffusive transport in ways that affect the use of the T-sensor to measure molecular properties.
- A further consequence is that, on the length scale of the cell, the oncoming velocity profile will be a quasisteady linear shear.
