Turning diffuser: development of performance correlations via asymptotic computational fluid dynamics technique
The performance of turning diffuser regardless of its expansion type, i.e., two-dimensional (2-D) or three-dimensional (3-D), has been traditionally rated using the guidelines established specifically for a 2-D turning diffuser. This has provided merely an approximation and has often led to an inac...

| Summary: | The performance of turning diffuser regardless of its expansion type, i.e., two-dimensional (2-D) or three-dimensional (3-D), has been traditionally rated using the guidelines established specifically for a 2-D turning diffuser. This has provided merely an approximation and has often led to an inaccurate prediction of 3-D turning diffuser performance. On top of that, the existing guidelines have just integrated the geometrical effect by discounting the effect of operating condition on the turning diffuser performance. Therefore, the current work aims:
(1) To experimentally and numerically investigate the performance of 2-D and 3-D turning diffusers for various geometrical and operating parameter.
(2) To develop performance correlations as a function of geometrical and operating parameters for 2-D and 3-D turning diffusers by means of Asymptotic Computational Fluid Dynamics (ACFD) technique.
