Nusselt numbers to characterize flow asymmetry

 

 

 

For a symmetric flow:   NuL–NuR = 0.

Bifurcation diagrams:

A=1     A=1.5        A=2     A=2 (extended)     A=2.3      A=2.8

 

A=4 (main branch)        A=4 (two additional branches)        A=6

 

A=6  for  Pr=10

 

 

Stability diagram for Pr=0.02

 

 

Examples of oscillatory flows:  A=2     A=6
