Abstract:
It has recently been shown that continuous wave lasers can generate steady, parametrically-analytic, laser-driven convective fluid flows (Lane, Fluids 2021), (Lane Stud. App. Math. 2024). We investigate the stability of these flows, by calculating their spectral data. Steady internally forced convection is contrasted to classic Rayleigh-Bernard convection. The spectrum is shown to be parametrically analytic at simple eigenvalues. The spectral data of large amplitude flows are computed, and dynamics near unstable flows are presented.
