| description | The invention belongs to the technical field of experimental viscoelastic fluid mechanics, and particularly relates to an experimental measurement method for elastic characteristic parameters of viscoelastic fluid constitutive. According to the method, the flexibility of a computational fluid mechanics modeling method and the ultrahigh precision of an Atomic Force Microscope (AFM) are utilized, and the experimental measurement method for the elastic characteristic parameters of the viscoelastic fluid constitutive is provided. Compared with the prior art, the method has the following technical effects: (1) the method is not limited by a viscoelastic constitutive form, and the theoretical model is adjusted aiming at the viscoelastic fluid to be measured, so that the measurement accuracy is improved; (2) by means of ultrahigh mechanical and displacement resolution of the atomic force microscope, the influence of weak elasticity in the dilute viscoelastic solution on mechanical characteristics in a flow field can |
