Shear Instabilities in Granular Flows down on Inclined Plane
Hua-Shu Dou, Boo Cheong Khoo, Nhan Phan-Thien
Instabilities at interface of two stream granular flows have been reported in recent experiment [1] that breaking waves can form at the interface between two streams of identical g…
Stability of Rotating Viscous and Inviscid flows
Hua-Shu Dou
Flow instability and turbulent transition can be well explained using a new proposed theory--Energy gradient theory [1]. In this theory, the stability of a flow depends on the rela…
Viscous Flow Instability of Inflectional Velocity Profile
Hua-Shu Dou
Rayleigh showed that inviscid flow is unstable if the velocity profile has an inflection point in parallel flows. However, whether viscous flows is unstable or not is still not pro…
On the Disturbance Equation of Flow Instability
Hua-Shu Dou
In this note, we propose a new idea by analyzing the basic disturbance equations, and give starting equations for understanding the instability phenomena of laminar flows and trans…
Threshold amplitudes for transition to turbulence in a pipe
Hua-Shu Dou, Boo Cheong Khoo, Khoon Seng Yeo
Threshold amplitude of disturbance for transition to turbulence in a pipe Poiseuille flow is investigated. Based on the energy gradient theory, we argued that the transition to tur…
Laws of Energy Gradient for Instabilities
Hua-Shu Dou
Transition to turbulence is due to the instability of a laminar flow subject to a disturbance. This complicated problem can be explained using a new proposed energy gradient theory…
