Abstract

The embodiment of the invention discloses a flow field determination method and device based on non-Newtonian fluid and a medium, and the method comprises the following steps: determining corresponding fluid viscosities of the non-Newtonian fluid under different shear rates through a pre-constructed non-Newtonian fluid rheological model, the non-Newtonian fluid rheological model is used for describing the corresponding relation between the viscosity and the shear rate of the non-Newtonian fluid; in the coating process of the non-Newtonian fluid, an initial coating die head flow field equation is established; according to the characteristics of the non-Newtonian fluid, determining initial conditions and boundary conditions of an initial coating die head flow field equation so as to determine a coating die head flow field equation meeting requirements; the fluid viscosity corresponding to different shear rates is input into the coating die head flow field equation meeting the requirement, the flow field of the non-Newtonian fluid is determined, the non-Newtonian fluid is modeled in combination with the fluid model and the coating die head flow field equation, the coating process of the non-Newtonian fluid can be truly simulated, and the accurate flow field condition is obtained.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular, to a method, device and medium for determining a flow field based on a non-Newtonian fluid. Background technique [0002] In recent years, with the rapid development of various components such as liquid crystal screens and solar panels, the development of coating technology has also attracted much attention. Coating is a key process that directly affects the capacity and consistency of the product. In the process design of the product, the polymer organic functional material is used to coat the substrate. [0003] In the existing coating technology, most of the coating materials are Newtonian fluids, and the simulation calculation also focuses on the simulation of the Newtonian fluid coating process. Most of the existing research models use commercial software to calculate the flow field. The fluid constitutive equation library of the software only supports Newtonian fl...
