dc.description.abstractDirect numerical simulations of magnetohydrodynamic turbulence with kinetic energy and cross helicity injections at large scales are performed. It was observed that cross helicity changes its sign as we go from large and intermediate scales to small scales. In addition, the magnetic reconnections are strongest in the regions, where the cross helicity changes the sign and becomes smallest in magnitude. Thus, our simulations provide an important opportunity to explore the regions of magnetic reconnections in nonlinear MHD.
dc.description.sponsorshipWe are grateful to Professor Franck Plunian for his interest in the subject and for useful comments. The developed mathematical model and the performed numerical simulations were supported by the Department of Science and Technology, India (INT/RUS/RSF/P-03) and by the Russian Science Foundation (RSF-16-41-02012) for the Indo-Russian project. Computational resources were provided by Shaheen II of the Supercomputing Laboratory at King Abdullah University of Science and Technology (KAUST) under project K1052. Theoretical studies of magnetic reconnection problems were also supported by the Japan Society for the Promotion of Science (JSPS) Grants-in-Aid for Scientific Research 18H01212. We thank the Scientific Committee of the Third Russian Perm Conference on Magnetohydrodynamics for organizing a warm atmosphere and stimulation discussions.
