Subsonic MHD-diffuser performance with high blockage

Computational Analysis of Flow performance in a C-shape Subsonic Diffuser

In the present investigation the distribution of mean velocity, static pressure and total pressure are experimentally studied on a C-shape diffuser of 40° angle of turn with an area ratio of 1.278 and centerline length was chosen as three times of inlet diameter. The experimental results then were numerically validated with the help of Fluent and then a series of parametric investigations are c...

Numerical Investigation of Subsonic Flow through an Aggressive Flat Bottom Diffuser

Date The final copy of this thesis has been examined by the signatories, and we Find that both the content and the form meet acceptable presentation standards Of scholarly work in the above mentioned discipline. Airflow through an aggressive, constant pressure gradient, flat-bottomed 2D diffuser is simulated with the compressible version of the stabilized, implicit finite element code PHASTA. T...

Diffuser Performance Appraisal a New Approach

A new approach to the evaluation of the performance of diffusers is presented. It is assumed that part of the juice in bagasse is easily extracted, by mill o r diffuser, and attention is therefore focussed on the remaining tightly-held or bound juice. This "difficult juice" is defined according to an analytical method. Preliminary results on the performance of diffusers, based on the extraction...

Improving the Hydrodynamic Performance of Diffuser Vanes via Shape Optimization

The performance of a diffuser in a pump stage depends on its configuration and placement within the stage. The influence of vane shape on the hydrodynamic performance of a diffuser has been studied. The goal of this effort has been to improve the performance of a pump stage by optimizing the shape of the diffuser vanes. The shape of the vanes was defined using Bezier curves and circular arcs. S...
