Flow angle
The most important as well as most difficult to measure aspects of flow measurement are flow conditions within a pipe upstream of a meter. Flow conditions mainly refer to the flow velocity profile, irregularities in the profile, varying turbulence levels within the flow velocity or turbulence intensity profile, swirl and any other fluid flow characteristics which will cause the meter to register flow different than that expected. It will change the value from the original calibration state referre…

WebFlow Deflection angle - (Measured in Radian) - Flow Deflection angle is defined as the angle by which the flow turns towards the oblique shock. Oblique shock angle - … Webpressures, angles of attack and sideslip, and air temperature should be determined to account for the disturbing presence of the aircraft in the flow field. The calibrations …
WebAt flow rates less than design, where the pressure rise is higher, the boundary layers are prone to separate and therefore the flow deviates from the angles at the trailing edges of the blades and turning is not as complete, thus reducing the … WebFlow angle is the direction in which the air is moving. θ n = F l o w a n g l e i n t h e n t h r e g i o n The Prandtl-Meyer angle is the angle at which the flow changes direction from one region to another. ν n = P r a n d t l - M e y e r a n g l e i n t h e n t h r e g i o n
