Title: Heating the corona by transverse waves: heating diagnostics from 3D models

Abstract: In this talk, I will discuss the recent 3D models of solar coronal loops and plumes that are driven with transverse waves that are launched from the lower, photospheric boundary. In the coronal loop simulations, the driving results in the efficient setting up of fundamental kink modes resembling decayless kink waves. We assess the correlation between the observed amplitude and the energy input in the system. In the coronal plume simulations, the photospheric driving launches propagating kink waves. These become turbulent via the new mechanism of uniturbulence. They can be observed to yield a correlation between Doppler shift and non-thermal line width, in line with theobservations.
