...Alan A. Thrift; Scott J. Brumbaugh; Karen A. Thole; Atul Kohli While the measurement of drag and lift forces on a body in external flow is common practice, the same cannot be said for aerodynamic forces on bodies in internal flows. The inherent difficulty in making force measurements on a body...

...C. Ruppel; T. Funke; F. Peters It is shown how to design a new method (DFFM) of flow metering in pipes from basic principles. The method relies on the well known drag force on a cylindrical body and the force measurement by a load cell. The drag force is exclusively measured in the axial flow...
