Non-Boussinésq conjugate natural convection in a vertical annulus

Non-Boussinésq conjugate natural convection in a vertical annulus with a centrally located vertical heat generating rod is studied numerically, taking into account variable transport properties. Results are presented for maximum solid temperatures, average Nusselt numbers and average pressure. In ge...

Beschreibung
Zusammenfassung:	Non-Boussinésq conjugate natural convection in a vertical annulus with a centrally located vertical heat generating rod is studied numerically, taking into account variable transport properties. Results are presented for maximum solid temperatures, average Nusselt numbers and average pressure. In general, the Boussinésq model predicts higher temperatures in the solid and lower average Nusselt numbers on the inner and outer boundaries.
