This paper introduces a lot of situations about the Computational Fluid Dynamics (CFD) analysis of backward facing step flows. The main point of this paper is incompressible flow in a backward step. measured by drivers and Seegmiller experiments. The researchers concluded that validation parameters chosen for the study are the locations of the surface hydrostatic pressure and the reat... https://www.spidertattooz.com/iOptron-HAE43EC-Strain-Wave-AZ-EQ-Mount-w-iPolar-High-Precision-Encoder/
