Introduction The erosion of liquid impact onto a solid target surface is general and significant to technological applications, such as steam turbine blades moving at high speeds through wet steam [1], aircraft and rockets flying at high speeds through rain, cleaning and cutting materials, et al.
In the Eulerian formulation, the mesh is stationary and the materials flow through the mesh.
As for the current study of impact velocity 100 m/s, it is modeled as an ideal plastic material, with its material constants listed in Table I.
The material constants for water are listed in Table II [10].

They are known to be among the most difficult-to-cut materials, the machinability of them are poor, especially the high cutting force and cutting temperature, short tool life and poor quality of the machined surface[1-2].

The composite materials generally exhibit superior characteristics than that of the matrix material.
The behaviour of hybrid composite materials is often sensitive to changes in temperature.
Good thermal control systems have been considered for various materials applicable for spacecraft applications.

Materials and Methods Field enclosure experiments Field enclosure simulation experiments were conducted in the western portion of Chaohu Lake, which is located at the Tangxi River Inlet in Yicheng, Hefei, China.
The filtered materials were then centrifuged at 10,000 rpm for 10mins using a JICA centrifuge (Japan), after which the supernatants were removed and placed in a graduated cylinder.
However, when the disturbance decreases or stops, viscous materials on the surface of Microcystis aeruginosa adhere to suspended solids and cause the algae to sink to the sediment surface[23-25].
