| 講演題目： |
Transition in Plane Parallel Shear Flows with an Internal Heat Source |
| 講演要旨： |
The transition from the uniform steady laminar flow to the chaotic motion of turbulent flow is of great importance in fluid dynamics. The main motivation behind the this research project is to study the pre-chaotic bifurcation behaviour of strongly non-linear equilibrium solutions for incompressible internally heated flow in a long channel. In particular it is envisaged that the solutions obtained will be related to the advanced stages of transition identified by the studies involving DNS and experimental investigations in the turbulent regime. During the talk results will be presented for the bifurcation behaviour of the strongly non-linear equilibrium solutions identifying therefore the mechanisms of transition for the fluid flow under the constant pressure gradient or constant flux conditions and for various values of the Prandtl number and of the angle of inclination of the channel flow. |
