Investigation of the Prediction of Losses in Radial Vaneless Diffusers

- H. Dou
- Engineering
- 3 June 1991

The non-dimensional width B and the inlet flow angle αi are the important parameters influencing the losses and the stability of radial vaneless diffusers. Their effects on diffuser losses are… Expand

The flow of an Oldroyd-B fluid past a cylinder in a channel: adaptive viscosity vorticity (DAVSS-ω) formulation

- H. Dou, N. Phan-Thien
- Mathematics
- 1 October 1999

Abstract A parallel unstructured finite volume method (FVM) is developed and implemented under a distributed computing environment through the parallel virtual machine (PVM) libraries, and is used to… Expand

Negative wake in the uniform flow past a cylinder

- H. Dou, N. Phan-Thien
- Physics
- 20 March 2003

The upstream/downstream streamline shift and the associated negative wake generation (streamwise velocity overshoot in the wake) in a viscoelastic flow past a cylinder are studied in this paper, for… Expand

Mechanism of flow instability and transition to turbulence

- H. Dou
- Physics
- 1 May 2006

Abstract In this paper, a new mechanism of flow instability and turbulence transition is proposed for wall bounded shear flows. It is stated that the total energy gradient in the transverse direction… Expand

Criteria of negative wake generation behind a cylinder

- H. Dou, N. Phan-Thien
- Physics
- 29 January 2004

It was demonstrated by simulation in our previous study that both the normal stress and its gradient are responsible for the negative wake generation (overshoot in the axial velocity) and streamline… Expand

Analysis of the Flow in Vaneless Diffusers With Large Width-to-Radius Ratios

The flow in vaneless diffusers with large width-to-radius ratios is analyzed by using three-dimensional boundary-layer theory. The variations of the wall shear angle in the layer and the separation… Expand
