Abstract: The nonlinear aeroelastic response of a two-dimensional airfoil with freeplay and cubic nonlinearities in supersonic flow were investigated. The second-order piston theory was employed to analyze a double wedge airfoil. Then, the fold bifurcation and the amplitude jump phenomenon were detected using...
Abstract: Unsteady peristaltic transport of Maxwell fluid in a finite tube was investigated. The walls of the tube were subjected to contraction waves that do not cross the stationary boundaries. The analysis was carried out by using long wavelength approximation in non-dimensional form. The expressions for a...
Abstract: The effect of magnetic field and nano particle on the Jeffery-Hamel flow were studied by a powerful analytical method that was called Adomian decomposition method (ADM). The traditional Navier-Stokes equation of fluid mechanics and Maxwell’s electromagnetism governing equations were reduced to nonli...
Abstract: Shock tube experiments of inclined Air/SF-6 interface instability under shock wave with mach numbers 1.23 and 1.41 were conducted, and were numerically simulated by the parallel algorithm and code MVFT (multi-viscous-fluid and turbulence) of large-eddy simulation (LES). The developing process of int...
Abstract: A numerical study of axisymmetric steady laminar incompressible flow of an electrically conducting micropolar fluid between two infinite parallel porous disks with constant uniform injection through the surface of the disks was carried out when the fluid was subjected to an external transverse magne...
Abstract: High-order implicit finite difference methods for solving the Stokes’ first problem for a heated generalized second grade fluid with fractional derivative were studied. The stability, solvability and convergence of the numerical scheme were discussed via fourier analysis and matrix analysis method. ...
Abstract: A very first combined application of finite element method (FEM) and differential quadrature (DQ) method to vibration and buckling problems of rectangular plates was presented. The mixed scheme combines the geometry flexibility of the FEM and high accuracy and efficiency of the DQ method. The accura...
Abstract: An integrated fluid-thermal-structural analysis approach, where the heat conduction in a solid was coupled with the heat convection in viscous flow of the fluid resulting in the thermal stress in the solid, was presented.The fractional four-step finite element method and streamline upwind Petrov-Gal...
Abstract: First, an explicit stress concentration factor expression for a tension finite-width strip with a central elliptical hole was formulated by using a semi-analytical and semi-empirical method. Comparing the results from this expression with those from Durelli’s photo-elastic experiment, Isida’s formul...
Abstract: The Dirichlet initial-boundary value problem of a compressible reactive gas model equation with nonlocal nonlinear source term was studied. For certain conditions, it is proved that the blow-up rate is uniform in all compact subsets of the domain and the blow-up rate is irrelative to the exponent of...
