چکیده
|
The aim of the present work is to analyze experimental and numerically the swirling turbulent flow in conical diffusers. the experimental part is made with particle image velocimetry (piv),where two geometries 5 and 10° semi-angles are analysed. we obtain information of the mean flow,in the axial and also in the cross sections of the swirling flow. in each piv plane,two velocity components are obtained. using the same conditions of the experimental apparatus,it is numerical simulation using cfx 14. we used reynolds averaged navier-stokes (rans) for solve the closing problem and shear stress transport (sst) turbulence modelling. in comparing the results,it was observed that the data had good quantitative agreement. © school of engineering,taylor’s university.
