This seminar shall comprise two parts; in the first part, the speaker shall discuss the design and implementation of Coriolis mass-flowrate meters for small flows. The discussion shall be based upon a use-case that the speaker has worked on as a part of his doctoral dissertation. After an introduction to the Coriolis measuring-principle, the scaling problem shall be discussed. The various mechatronic design approaches taken to extract a minuscule Coriolis-force from a dynamic system shall be touched upon - a.o. contactless actuation and sensing, the placement of eigenfrequencies and mode-shapes, and the purely temporal measurement-extraction method. Challenges encountered, such as parasitic vibrations transmitted to the environment, shall also be dealt with. In the second part, the speaker shall discuss the need for, and some simple design-rules for magnetic path design and magnetic shielding - be it for Lorentz-actuators, shielding against parasitic ground-loops or shielding at nT-levels for e-beam applications.
Aditya Mehendale works at Philips Innovation Services at Eindhoven as a senior technologist since 2011. Before this, he has worked at Demcon Advanced Mechatronics in Oldenzaal as a mechatronics engineer and at the University of Twente as a post-doctoral researcher. He has completed his PhD in 2008 and his Masters' (Mechatronics) in 2003 both at the University of Twente (NL), and before that his Bachelors' in 1998 (Electronics engineering) at the University of Pune. Aditya has several patents in diverse fields such as positioning systems for oncology, sensors, shielding for e-beam lithography and Coriolis mass-flow meters. His current interest is in sensors and additive manufacturing.
