Magnetohydrodynamic (MHD) waves are regularly observed in the finely structured, highly dynamic solar atmosphere. This dynamic behavior in plasma environments gives rise to plasma flows, that can lead to the instability of waveguides. Recent studies have employed the method of introducing waveguide asymmetry to generalise ‘classical’ symmetric descriptions of the fine structuring within the solar atmosphere, with some of them introducing steady flows as well. The presentation will share our analytical investigations validated by numerical simulations on how the phase speeds of the guided waves change, and where possible, determine the limiting flow speeds required for the onset of the Kelvin-Helmholtz instability (KHI).
