A Kiel probe is a device for measuring
stagnation pressure or
stagnation temperature in
fluid dynamics
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids— liquids and gases. It has several subdisciplines, including ''aerodynamics'' (the study of air and other gases in motion) an ...
. It is a variation of a
Pitot probe
A pitot ( ) tube (pitot probe) measures fluid flow velocity. It was invented by a French engineer, Henri Pitot, in the early 18th century, and was modified to its modern form in the mid-19th century by a French scientist, Henry Darcy. It is ...
where the inlet is protected by a "shroud" or "shield." Compared to the Pitot probe, it is less sensitive to changes in
yaw angle, and is therefore useful when the probe's alignment with the flow direction is variable or imprecise.
