Tertiary and quaternary solutions for plane Couette flow with thermal stratification
- 600 Downloads
Numerical solutions describing steady wavy rolls are obtained for a horizontal Couette layer heated from above. Two different Prandtl numbers have been investigated, P = 0.71 and P = 7, but most of the results depend only on the Grashof number G. The stability of wavy solutions is analyzed with respect to disturbances that do not change the horizontal periodicity interval. Oscillatory quaternary solutions bifurcating from the steady wavy rolls have been obtained through forward integrations in time.
