| Abstract: | In order to analyze the microscopic stress field acting on residual oil droplets in micro pores,calculate its deformation,and explore the hydrodynamic mechanism of viscoelastic fluids displacing oil droplets,the viscoelastic fluid flow equations in micro pores were established by choosing the upper-convected Maxwell constitutive equation.The numerical solutions of the flow field were obtained by volume control and alternate direction implicit methods.The velocity field and microscopic stress field,the force... |
