| 1 | Experimental investigation of time-dependent cavitation in an oscillatory squeeze film显示文摘The occurrence of time-dependent cavitation and tensile stress in an oscillatory oil squeeze film were investigated experimentally. The test apparatus was a simple thrust bearing consisting of two parallel circular plates separated by a thin viscous oil film. During the test, one plate was at rest while the other (transparent) oscillated in a direction normal to its surface. This test configuration was chosen to avoid the rotational motion and complicated geometry of a squeeze film journal bearing. The frequency of oscillation was in the range of 5 to 50 Hz and was controlled by an electro-magnetic exciter. The process of cavity formation and its subsequent development was recorded by a high-speed video camera. Concomitant pressure in the oil film was measured both within and without the cavitation region. It was found that both tensile stress and cavities existed in a squeeze film under certain working conditions. | CHEN Xiaoyang, SUN Meili, WANG Wen, D. C.

| 2 | Fast Fourier-Galerkin methods for first-kind logarithmic-kernel integral equations on open arcs显示文摘We propose a fully discrete fast Fourier-Galerkin method for solving an integral equation of the first kind with a logarithmic kernel on a smooth open arc,which is a reformulation of the Dirichlet problem of the Laplace equation in the plane.The optimal convergence order and quasi-linear complexity order of the proposed method are established.A precondition is introduced.Combining this method with an efficient numerical integration algorithm for computing the single-layer potential defined on an open arc,we obtain the solution of the Dirichlet problem on a smooth open arc in the plane.Numerical examples are presented to confirm the theoretical estimates and to demonstrate the efficiency and accuracy of the proposed method. | WANG Bo1,WANG Rui2 & XU YueSheng3,4,1Academy of Mathematics and Systems Science,Chinese Academy of Sciences,Beijing 100190,China 2School of Information Science and Engineering,Graduate University of the Chinese Academy of Sciences,Beijing 100190,China 3Department of Mathematics,Syracuse University,Syracuse,NY 13244,USA 4Department of Scientific Computing and Computer Applications,Sun Yat-sen University,Guangzhou 510275,China | 2010 | Science China Mathematics2010，53，1： | 3 |
