Description

The coronal heating problem and the generation of the solar wind remain central challenges in solar physics, both of which require a detailed understanding of wave-based heating mechanisms. In this study, we investigate the turbulent cascade of kink and Alfv\'en wave energy and its role in heating the solar atmosphere and driving the solar wind, through a newly implemented physics module in MPI-AMRVAC called UAWSOM. We assess the heating efficiency of kink waves in comparison to traditional Alfv\'en waves which necessitate an anomalous background heating function for numerical stability. We demonstrate that kink wave driven (UAWSOM) models forgo this requirement by demonstrating that a stable coronal atmosphere can be maintained using only kink waves.
