In this thesis, we consider the phenomenon of angular momentum transport in magnetically confined plasmas. Relevant experiments and theoretical developments are presented in order to motivate the derivation of a modified version of the three-field nonlinear Hamaguchi-Horton equations. The equations are altered to include a zeroth-order parallel velocity inhomogeneity along the radially-analogous coordinate, resulting in a nonlinear system that describes the evolution of the velocity-ion temperature gradient-driven modes (VITGs). The equations are used to analyze VITG modes in the local approximation of a magnetized plasma, as well as in an inhomogeneous slab model. Applying quasilinear methods, we find a turbulent angular momentum flux in agreement with the accretion theory of the spontaneous rotation phenomenon. More advanced applications are considered for future analysis.","abstract_html":"Plasma confinement experiments continue to uncover fascinating phenomena that motivate theoretical discussion and exploration.
