Liam Barnes is a 3rd year undergraduate student at the University of Newcastle, completing a double degree in Mathematics and Science. His Mathematics major is pure/applied mathematics and his Science major is Physics. His research interests include Solar Physics, Theoretical Physics and Functional Analysis. He is passionate about developing our understanding of the world around us for the betterment of society, and believes mathematics and physics is where he can make the greatest difference. Liam is hopeful that this research project, where he aims to compare the Coriolis and Lorentz forces on plasma flows on the Sun’s surface, will further develop his understanding and knowledge in mathematical physics and prepare him for further research in Honours and postgraduate study.
In his spare time, Liam enjoys working out at the gym, playing videogames and hanging out with mates.
Coriolis Force acting on Magnetic Active Regions on the Sun
The aim of this project is to compute the effect of the Coriolis effect on all of the flows generated as an active region forms at the surface of the Sun, simulated by three-dimensional magneto-hydrodynamic simulations of the near-surface convective layers including the effects of solar rotation. From the simulations we have access to the full three-dimensional components of the flows and the magnetic field as a function of height.
We will use (pre-computed) state-of-the-art three-dimensional magnetohydrodynamic (MHD) simulations of emerging active regions in the near-surface layers of the Sun to calculate the effect of the Coriolis force on different flows and compare it to the Lorentz force and magnetic tension in the MHD equations.
