  • System of numerical analysis of finite depth dip coating process
    • Prediction of the shape of coated layer varying system parameters.
    • Phase field method
      • Based on an Eulerian description, it is widely used in deformable domain problems such as pinch-off and coalescence dynamics.
    • ALE method
      • Track the position of the mesh nodes in a Lagrangian fashion by integrating the evolution equation.
    • Governing Equation
      • To simulate the pinch-off dynamics, we adopted the NSCH(Navier-Stokes-Cahn-Hilliard) equation as a governing equation.
  • Procedures and results of dip coating process
    • Procedure
      • After the initialization of field variables, we wait until the fluid wet the solid surface.
      • Then, simulate the pulling process by moving mesh.
    • Results
      • We can simulate the finite depth dip coating process in 2D and 3D cases.
