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…
Determining the Critical Condition for Flow Transition in a Full-Developed Annulus Flow
Hua-Shu Dou, Boo Cheong Khoo, Her Mann Tsai
Axial flow in an annulus between two concentric cylinders is commonly seen in various flow devices used in chemical processing industries and petroleum science and engineering. The…
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…
Instability of Taylor-Couette Flow between Concentric Rotating Cylinders
Hua-Shu Dou, Boo Cheong Khoo, Koon Seng Yeo
The energy gradient theory is used to study the instability of Taylor-Couette flow between concentric rotating cylinders. This theory has been proposed in our previous works. In ou…
Energy Loss Distribution in the Plane Couette Flow and the Taylor-Couette Flow between Concentric Rotating Cylinders
Hua-Shu Dou, Boo Cheong Khoo, Khoon Seng Yeo
The distribution of energy loss due to viscosity friction in plane Couette flow and Taylor-Couette Flow between concentric rotating cylinders are studied in detail for various flow…
Investigation of Turbulent transition in plane Couette flows Using Energy Gradient Method
Hua-Shu Dou, Boo Cheong Khoo
The energy gradient method has been proposed with the aim of better understanding the mechanism of flow transition from laminar flow to turbulent flow. In this method, it is demons…
