The correlation between the special theory of relativity and subsonic compressible fluid mechanics
… equation 19.5 is an exact relation between the compressible and incompressible local pressure coefficients. Nowhere in the preceding analysis was it necessary to make simplifying assumptions such as small perturbations, etc. It is true that the Sound-Space Theory assumes steady …

Infiltration of a Two-State Compressible Fluid Through a Linearly Deformed, Porous, Elastic, Fissured Rock
… to calculate solid displacements and stresses, fluid pressures and flows. The numerical examples include a one-dimensional column, a two-dimensional layer, and a two-dimensional halfspace of fissured rock. The selected examples indicate that the double porosity model predicts larger …

The simulation of single phase, compressible fluid flow in fractured petroleum reservoirs using finite elements
… commonly used equations governing the flow of fluids are reviewed, from first principles where appropriate. The assumptions that are made in the process are critically assessed and their limitations are discussed. The equations deal with flow through a porous and permeable medium, a single …

Application of the hodograph method to several problems in fluid mechanics
… of stead, two-dimensional, irrotational, compressible fluid motion in which the bounding streamlines are made up partially of straight boundaries and partially of free streamlines. As in classical theory, these solutions can be used to determine important physical characteristics of the …

A groupoid approach to geometric mechanics
… variations of a rigid body in an inviscid fluid. The different cases are specified by the properties of the fluid; the fluid may be compressible or incompressible, irrotational or not. By using groupoids we generalize Arnold’s diffeomorphism group framework for fluid flows to show that the …

Pulse Propagation in Fluid-Filled Elastic Curved Tubes
The propagation of fluid transients through elbows in pipes is an important consideration in the safety analysis of nuclear piping systems. In this study, one-dimensional governing equations for the propagation of pressure pulses in an inviscid compressible fluid contained in a thin-walled …

A Numerical Study of Unsteady Natural Convection in a Rectangular Enclosure -- The Effect of Variable Thermodynamic and Transport Properties
… inside a rectangular enclosure filled with a compressible fluid where one of the vertical walls of the enclosure is kept at a higher temperature than the opposite one. Fluid thermodynamic and transport properties are assumed to be functions of temperature. The governing equations are …

An optimization approach to well spacing for gas storage reservoirs
… the conventional diffusivity equation describing compressible fluid flow through porous media has been developed with a view to apply it to the problems of optimum well spacing. An equilateral grid system has been employed to enable uniform well spacing for any number of wells. A numerical model …

A two-dimensional fluid-structure coupling algorithm for the interaction of high-speed flows with open shells
… this work, an algorithm for simulating the solid-fluid interactions of a highly-deformable open shell structure and a compressible fluid flow is presented. The main objective is to extend the algorithm previously presented by the authors to the case of open shell structures immersed in a fluid. …

Adaptive stable finite-element methods for the compressible Navier-Stokes equations
Many problems involving fluid flow can now be simulated numerically, providing a useful predictive tool for a wide range of engineering applications. Of particular interest in this thesis are computational methods for solving the problem of compressible fluid flow around aerodynamic configurations. …

Design optimization of oxygenated fluid pump
… Kheir from Boston Children's Hospital created a compressible fluid that can re-oxygenate blood quickly in patients with asphyxia and cardiac arrest. Because the fluid is compressible, the set infusion rate on an ordinary pump does not necessarily indicate what is delivered. In addition, the fluid …
