MATHEMATICAL MODEL FOR THIN-PLATE FLOW OF INCOMPRESSIBLE NON-NEWTONIAN VISCOUS FLUIDS
【摘要】 建立了描述非牛顿粘性流体薄板流的数学模型,给出了单口浇注过程注射压力计算公式,并讨论了充分发展的矩形薄板流问题解的存在唯一性及求解方法.
【Abstract】 A two-dimensional mathematical model for the thin-plate flow of incompressible non-Newtonian viscous fluids is established. The formula for calculation of the injection pressure in injection process with single gate is obtained, and an existence and uniqueness theorem for rectangular thin-plate flow is proved.
