Revisiting Hua-Marcus-Bellman-Ando Inequalities on Contractive Matrices
No full textLoo-Keng Hua showed some elegant matrix and determinant inequalities via a matrix identity and proved the positive semidefiniteness of a matrix involving the determinants of contractive matrices through group representation theory. His study was followed by M. Marcus, R. Bellman and T. Ando. The purpose of current paper is to revisit the Hua’s original work and the results of Marcus, Bellman and Ando with our comments, and to present analogs and extensions to their result

DNS of turbulent channel flow with a flexible square cylinder
No full textFluid-Structure Interaction (FSI) problem is concerned with in various research fields such as mechanical, aerospace, civil and medical engineering. Their accurate prediction and control are desired. So far, in order to improve the performance of various applications, many kind of research, on the heat transfer enhancement due to vortex generator in heat exchangers, on the drag reduction through the setting of bluff body in pipe-line systems, and on the reduction of flow induced vibration, are conducted. In particular, since the wake of wall-mounted cylinder is a common flow regime in above-mentioned research, the detail of the flow has been aggressively investigated so far[1]. The present study, we pay attention to the flow control using flexible structures in the above mentioned flows. To investigate the potentiality of the control in advance, both high accurate and stable computational scheme is needed so that theactual phenomena including turbulence is well predicted. Therefore, in order to analyze the fluid-structure interaction, we propose aweak-coupling method[2] in which for flexible structures, the rigorous equations of motion are discretized with finite volume method (FVM[3]); for a flow computation, the finite difference method (FDM) is used and the flexible structures is reproduced via immersed boundary method[4]. In this present paper, we demonstrate on the result of flow structure around of rigid and elastic cylinder in turbulent channel flow
