The structure and the frequency spectra of wall pressure fluctuations beneath a planar turbulent boundary layer interacting with conical shock wave at Mach number $M_\infty =2.05$ Reynolds $\textit {Re}_\theta \approx 630$ (based on upstream momentum thickness) are examined to elucidate effects gradient flow separation characteristics fluctuations, by exploiting direct numerical simulation data...

In dimension $n=3$, there is a complete theory of weak solutions Ricci flow - the singular flows introduced by Kleiner and Lott which are unique across singularities, as was proved Bamler Kleiner. We show that uniqueness should not be expected to hold for in dimensions $n\geq5$. Specifically, we exhibit discrete family asymptotically conical gradient shrinking solitons, each admits non-unique f...

in the present study, experimental investigations about the hydrodynamics of the conical cap tray (concap tray) have been carried out. the concap tray is an innovative and novel type of cap trays. the effect of the different weir height (2.5, 5 and 7 cm) on the weeping, entrainment and the total pressure drop for the concap tray was measured, compared and correlated. the hydraulic experiments w...

Using Donnell-type shell theory a simple and exact procedure is presented for linear buckling analysis of functionally graded conical shells under axial compressive loads and external pressure. The solution is in the form of a power series in terms of a particularly convenient coordinate system. By analyzing the buckling of a series of conical shells, under various boundary conditions and diffe...

Abstract— The main aim of this study was to control the nonlinear process using multi-model PI controller. A multi model is developed for conical tank and it is validated against the real time setup conical tank process. A Multi model based PI controller is also developed, and implemented with realtime setup, and their performances are compared with that of the conventional controller of real t...
