abstract = {<p style="text-align: justify;">In this paper, we present an immersed boundary method for simulating
moving contact lines with surfactant. The governing equations are the incompressible
Navier-Stokes equations with the usual mixture of Eulerian fluid variables and Lagrangian
interfacial markers. The immersed boundary force has two components: one
from the nonhomogeneous surface tension determined by the distribution of surfactant
along the fluid interface, and the other from unbalanced Young&#39;s force at the moving
contact lines. An artificial tangential velocity has been added to the Lagrangian
markers to ensure that the markers are uniformly distributed at all times. The corresponding
modified surfactant equation is solved in a way such that the total surfactant
mass is conserved. Numerical experiments including convergence analysis are
carefully conducted. The effect of the surfactant on the motion of hydrophilic and
hydrophobic drops are investigated in detail.</p>},
