ProfessorYasuhide Fukumoto will be on campus this week to present results on researchbased in fluid dynamics. University of Antelope Valley Mathematics ProfessorTaxpulat Ruzi Ph.D. collaborated with Fukumoto on the theory for "thesteady motion of a spherical vortex of a conducting fluid subject to the Hall effect. Fukumoto is the Director of Institute of Mathematics for Industryat Kyushu University - one of seven major national universities in Japan. Also,he is the Director Japan Society of Fluid Mechanics
ProfessorFukumoto will be speaking at the 67th Annual Meeting of the American PhysicalSociety's Division of Fluid Dynamics (APS-DFD) in San Fransisco. The meeting ishosted by Stanford University, UC Berkeley, and Santa Clara University
Dr.Yasuhide Fukumoto is scheduled to arrive at the University of Antelope Valleyon November 21, 2014. The presentation will begin at 3:00 pm in the East Wingof the Grand Ballroom. The Grand Ballroom is located at 44055 N. Sierra Hwy.,Lancaster, CA 93534
If you areinterested in attending the presentation and meeting Dr. Fukumoto, please feelfree to come to this event. You are more than welcome to attend this event toask questions relating mathematics and physics
Title:
Topological ideas in magnetohydrodynamics (MHD) and its application tomagnetorotational instability (MRI)
Abstract:
This seminar starts with an outline of derivation of the equations describingthe magnetohydrodynamics (MHD), namely, dynamics of an electrically conducting fluidsubject to a magnetic field. Then topological invariants of an ideal MHD areexpounded. These invariants imply preservation of the link and knot types ofmagnetic-field lines and 'generalized' vortex-lines
Ingalaxies, stars are formed at the center of accretion disks by absorbingmatters. Since the total angular momentum is conserved, the angular momentummust be transported away while the mass is absorbed to the center. Themagnetorotational instability (MRI) is a desired mechanism for triggering turbulencenecessary to account for outwards transport of the angular momentum. The latterhalf of the seminar is devoted to show our recent contribution to thethree-dimensional MRI in the presence of toroidal field
