An accurate method for evaluating surface tension force was proposed. The method utilizes a solution of the Cahn-Hilliard equation for the color function of the Continuum Surface Force model. Curvature vectors on three surfaces of revolution, i.e., sphere, distorted spheroid and spherical-cap were accurately evaluated by the method. Interface tracking simulations of a flow around a neutrally buoyant fluid sphere and of a drop rising through a stagnant liquid demonstrated that the proposed method could significantly reduce pseudo parasitic currents caused by numerical errors in surface tension force.
