AWSOM-type models (Van der Holst et al. 2014) have been very successful in describing the solar atmosphere by incorporating Alfven wave driving as extra contributions global MHD equations. However, they lack from other modes. In this paper, we aim to write governing equations for energy evolution equation of kink waves. a similar manner AWSOM, combine with MHD. Our goal is incorporate heating provided uniturbulent damping We attempt construct UAWSOM (uniturbulence and driven models). recently described terms Q-variables. These latter variables allow follow waves co-propagating reference frame. transform Q-variable into an equation. First do generally, then specialise description also couple slowly varying formulation solve system 1D. find that contains non-linear terms, even absence counterpropagating The expressed solely through equilibrium parameters, rather than ad-hoc perpendicular correlation term, case AWSOM models. A proof-of-concept numerical implementation python shows indeed leads radial outflow heating. Thus, may necessary ingredients drive wind heat corona against losses. Not only does our current work constitute pathway fix shortcomings popular model, it provides mathematical formalism more modes additional wind.
