Physics Department Seminar-FR

Event Details:

This event will be held on Thursday, Nov. 25, from 1:15 - 2:15 p.m., via Microsoft Teams (contact physics@unb.ca for link to join).

Speaker:  Duncan Osmond, UNB Fredericton Physics

Topic: "Magnetic Resonance methods for characterization of dispersed media"

"Dispersed media such as sprays play a role in many modern systems from fuel injection in engines to fertilization in agriculture. Characterization of spray dynamics is almost entirely accomplished through optical methods in industry at present. Magnetic resonance (MR) methods show promise as alternative probing methods in situations where optical methods fail, such as enclosed/opaque systems or dense spray regimes. Velocities within spray systems often greatly exceed those typically examined with MR methods, presenting new challenges. Present work investigates several methods for the estimation of velocity within a known spray system, including Pulse Field Gradient method and Dynamic Magnetic Resonance Scattering, a novel method derived from optical microscopy. Velocity is estimated and compared across different methods, employing a variety of MR techniques in the process."

NOTE: Seminar event starts at 1 p.m. to allow the speaker time to set up and time for attendees to have an open chat until the seminar start time of 1:15 p.m.
