Stability of differentially heated flow from a rotating sphere
作者:
Highlights:
• Differentially heated flow of a thin fluid layer from a rotating sphere has been investigated.
• A numerical solution procedure for solving the steady and unsteady equations has been proposed.
• An approximate analytical solution has been derived.
• A linear stability analysis has estimated a theoretical value for the onset of instability.
• Good agreement was found between numerical, analytical and theoretical results.
