摘要: The present paper, which consists of two parts, proposes models fluid flow in grinding with nonporous wheels. In this first part, a smooth wheel is employed instead rough to simplify the analysis. Fluid investigated for laminar and turbulent regimes using classical Reynolds equation lubrication modified flows, respectively. applicability proposed discussed verified experimentally terms developed hydrodynamic pressure. It found that reliably predicts pressure if number Re (based on minimum gap size) lower than about 300. Experimental results 300
