An analytical investigation and conceptual design of a disk-shaped asymmetric heat pipe is presented in this work. Using the conservative formulations for the steady incompressible vapor and liquid flow for a disk-shaped heat pipe, an in-depth integral analysis is applied. Analytical results for the asymmetric vapor velocity profile, the vapor and liquid pressure distributions, and the vapor te...
In this paper, the weighted sum of spatial gradients, or WSSG (formerly known as composite velocity) is developed for use in active structural acoustic control (ASAC) on clamped flat rectangular plates. In previous work, WSSG was developed on a simply-supported flat rectangular plate\cite{pseudo}, and showed promise as a control metric. The displacement on the clamped plate has been modeled usi...
In this study buckling analysis of solid rectangular plate made of porous material in undrained condition is investigated. The mechanical properties of plate are assumed to vary through the thickness direction. Distributing of the pores through the plate thickness are assumed to be the nonlinear nonsymmetric, nonlinear symmetric, and monotonous distribution. The effect of pores and pores distri...
Abstract : In this research, active control of vibrations of a simply supported rectangular plate is investigated by a new method. At first, differential equation of motion of a plate with piezoelectric patches is developed by means of classical plate theory in order to apply in this method, and a local function is used for applying the mass and stiffness effects. Then, natural frequencies an...
