Measurement of Flow angle and Torque of Turbomachineries

This course covers two significant aspects of fluid mechanics: the measurement of flow angles using mechanical probes and torque measurement using dynamometers. For instance, in the context of turbo machines, students learn about the importance of flow angles in characterizing the turbo machines flow field and their direct relation to the phenomenon of work interchange. The course also delves into the calibration of mechanical probes and the operational principle of these probes. On the other hand, the course explores the concept of torque measurement using a dynamometer, its role, challenges, and importance in measuring torque in the context of internal combustion engines and hydraulic turbines. The operational principle of a prony brake, a type of dynamometer, is also discussed, along with potential sources of error in power measurement.
