Excitation of wave packets and random disturbances in a boundary layer
… made possible to verify regions of the neutral-stability curve. In the case of wave-packet creation it was found that the wave packets behave like a structure that consists of waves of certain frequencies that grow or decay not necessarily according to the stability curve but in that way as to …

Dedução do incremento das forças de corte dinâmico ortogonal e sua aplicação para previsão da carta de estabilidade, num modelo simplificado de máquina operatriz
… the atability chart and the unconditional stability curve of the model. This curve was compared with the unconditional stability curve, obtained from the exiating equations and with the experimental curve, obtained with the model of machine tool. Making use of the tool holder response, with …

Stability of a condensate film flowing down a vertical plane
… condensate film are formulated. The linearized stability problem is derived under the parallel flow assumption. A second—order perturbation solution of the stability problem is presented using the Nusselt solution as base flow. The boundary layer equations of laminar film condensation are solved …

Analysis for Taylor vortex flow
… of the basic problems of nonlinear hydrodynamic stability. In contrast with the wide region of wavenumber predicted by the linear theory, experiments show that Taylor vortex flow only appears in a small region containing the critical wavenumber ß<sub>er</sub> This phenomenon is called wave …

Experimental Study of the PVTX Properties of the System H₂O-CH₄
… also been conducted to determine methane hydrate stability over the temperature range of -40~20°C. Synthetic fluid inclusions were employed in both studies as miniature autoclaves. Experimental data for the PVTX properties of H₂O-CH₄ fluids under late diagenetic to low grade metamorphic conditions …

The Tollmien-Schlichting instability of laminar viscous flows
… work, an analysis of the Tollmien-Schlichting instability of laminar viscous flows is presented. For two-dimensional incompressible flow past a flat plate with porous suction strips, we use linear triple-deck, closed-form solutions for the mean flow to do a linear, parallel, spatial stability …

Impact of Hydrate Dissociation on the Stiffness and Strength of Hydrate Bearing Sands
The escalating global energy demand has propelled the exploration of unconventional energy resources, notably natural gas hydrates. These ice-like compounds, abundant in permafrost and marine sediments, harbor vast quantities of methane, a potent energy source. However, conventional methods for …
