Review on Mathematical Models of Moving Contact Line and Dynamic Contact Angle
The Huh-Scriven paradox shows that under the continuum assumption,if the solid wall is specified with no slip boundary condition,the velocity at the moving contact line will be indescribable and the mechanical singula-rity will be caused.Based on the mechanical singularity of the moving contact line and its elimination mechanism,the multi-scale characteristics of the moving contact line are discussed from the microscopic point of view.The mathematical model of the dynamic contact angle in the wetting process is summarized,and several processing meth-ods for the velocity of the moving contact line in the simulation process are also discussed.
