Pure Surface

We present numerical computations of the deformation of an oil-droplet under the influence of a surface tension gradient generated by the surfactant released at the poles (the Greenspan experiment). We find this deformation to be very small under the pure surface tension gradient. To explain the large deformation of oil droplets observed in Greenspan’s experiments, we propose the existence of a phoretic force generated by the concentration gradient of the surfactant. We show that this hypothesis successfully explains the available experimental data and we propose some further tests.

Major Factors

Through the numerical simulation research about the deformation and stability of cut-off wall´s foundation trench in Zhikong Hydropower Station China [1]. The text explained the major factors which were construction scheme and the strength of interior bracing structure of the deformation and stability about the foundation trench. In the early construction, the two reasons caused the large deformation. When adjusted the construction scheme and the strength of interior bracing structure, the deformation state of foundation trench and supporting system became much better.
