Aimed at the waves of thin gauge products and the limitation of leveling strip head or tail in temper mill,the function of leveling strip head has been developed and applied in production in Zhujiang Steel.

Cold-rolled electric steel should not only have excellent magnetic property,but good wave shape as well,according to customers' requirements.

Abastract In this paper,the classification of strip shape and the reasons to cause waves in practical producing are introduced.

Nonlinear dispersion effect on wave transformation;

A numerical method based on potential theory was developed to simulate nonlinear wave transformation over a submerged breakwater.

Numerical simulation of wave pressures and wave motions on complicated composite seawalls;

The Research on Wave Deformation by Using PLIC-VOF;

The parabolic wave equation is used to establish a wave model, by which the wave deformations, including wave breaking and wave diffraction,are studied.

A comprehensive numerical model for wave deformation and wave breaking plays an important role not only in practical application but also in theoretical research.

The amplitude and energy produced by the tester are similiar to the surge waveform produced by the practical surge disturbing wave.
