چکیده مقاله:

In this paper, an analytical formula to calculate the radial stiffness of groove elastic support is presented. The influence of structure parameters on radial stiffness and homogeneity of radial stiffness is investigated as well. The accuracy and calculating speed of the analysis formula are compared to that of finite element method (FEM). Findings are as following: The calculating speed of analysis formula is more efficient than that of finite element method (FEM). When the number of groove is less than 20, the maximum relative error of two methods is less than 10%. The radial stiffness of groove elastic support increases with the groove number, thickness of arc beam and transition angle, but decreases with the groove gap. The radial stiffness changes slightly and periodically with the azimuth angle of radial load, and the greater groove number and the thinner thickness of arc beam, the more homogeneous radial stiffness of groove elastic support.

Calculation of Complicated Flows, Using First and Second-Order Schemes (RESEARCH NOTE)

The first-order schemes used for discretisation of the convective terms are straightforward and easy to use, with the drawback of introducing numerical diffusion. Application of the secondorder schemes, such as QUICK scheme, is a treatment to reduce the numerical diffusion, but increasing convergence oscillation is unavoidable. The technique used in this study is a compromise between the above-...
