Rheological characterisation of abrasive media and

Flow field simulation of abrasive media in a constrained passage in abrasive flow machining (AFM) plays a decisive role in optimising process parameters and designing the core of a fixture. Based on the experimental rheological characterisation of various types of abrasive media, a model of flow field simulation of abrasive media was constructed by combining with the continuous medium hypothesis.
