Hence, compressibility effects within the viscoelastic regime may become important and influence resulting flow phenomena. From a physical perspective, the difference between incompressible and compressible flows lies in the propagation of longitudinal acoustic waves transmitted through the by: Ohmic diffusion in a rotating incompressible liner. The liner motion is calculated from applied surface pressure and body forces, and a self-sustaining cycle is defined by the liner returning to its initial position. The effects of compressibility on the results are dis-cussed by using a . In the large-eddy simulation of variable-density flows, these processes manifest themselves as subgrid-scale (SGS) terms that interact with the resolved-scale flow. This paper studies the effect of the variable-density SGS terms and quantifies their relative by: 6. Numerical results are obtained for a prescribed model radial trajectory and presented as a function of the compression ratio and Reynolds number. 2. Analytical treatment The liquid liner is assumed to undergo a flow in the r, 4 plane corresponding to the motion of an infinite hollow cylinder which is imploding while rotating about its by: 1.

swell ﬂow are presented and discussed. To study the effects of compressibility, two alternative equations of state, a linear and an exponential one, are used. A linear equation of state has been employed in previous numerical studies of the compressible extrudate swell ﬂow (Beverly and Tanner ; Georgiou ), by. Compressibility effects on the Rayleigh-Taylor instability growth between immiscible fluids Article (PDF Available) in Physics of Fluids 16(1) January with 90 Reads How we measure 'reads'Author: Daniel Livescu. A numerical scheme of study is developed to model compressible two-fluid flows simulating liquid sloshing in a partially filled tank. For a two-fluid system separated by an interface as in the case of sloshing, not only a Mach-uniform scheme is required but also an effective way to eliminate unphysical numerical oscillations near the by: An analytical solution is derived for the two-dimensional, laminar, compressible, planar free jet. The solution assumes constant pressure, specific heats, and unity Prandtl number and accounts for the effects of heat conduction and viscous dissipation in a self-consistent fashion. Exact closed-form expressions are provided for the streamwise and transverse velocities, temperature, vorticity Cited by:

The paper studies the effects of liquid-liner viscosity on the motion of a rotating imploding circular liner in the realistic limit of large Reynolds number. It is found that viscous effects are concentrated in a thin boundary layer at the free surface whose thickness is of the order of the inverse of the square root of Reynolds number. The numerical simulation of turbulent flows is a subject of great practical importance to scientists and engineers. A combined experimental and numerical investigation of the heat transfer characteristics inside an impingement cooled combustor liner heat shield has been conducted. Due to the complexity and irregularity of heat shield configurations, standard correlations for regular impingement fields are insufficient and detailed investigations of local Cited by: Effects of Perforated Liners on Controlling Combustion Instabilities in Annular Combustors.
