Thermal convection of a viscoplastic liquid with high Rayleigh and Bingham numbers (original) (raw)

This paper investigates the thermal convection of a viscoplastic liquid characterized by high Rayleigh and Bingham numbers. The study focuses on analyzing the stability of convection in a closed loop, providing insight into how yield stress affects dynamics as opposed to classical viscous liquids. The findings indicate that a stable motionless solution persists at lower Rayleigh numbers, while higher numbers lead to complex behaviors such as steady circulation and potential chaotic oscillations.
