Disc-planet interactions in inviscid discs
Planets are born in protoplanetary discs (PPDs), made of gas and dust, which surround newly formed stars. Gravitational coupling provides planets with means to interact with their birth environment, leading to the excitation of global spiral density waves, which drive evolution of the disc (such as …

Viscous-inviscid interactions of dense gases
The interaction of oblique shocks and oblique compression waves with a laminar boundary layer on an adiabatic flat plate is analyzed by solving the Navier-Stokes equations in conservation-law form numerically. The numerical scheme is based on the Beam and Warming’s implicit method with approximate …

Viscous-inviscid interaction for incompressible flows over airfoils
… boundary layer which interacts with an external inviscid flow. Numerical methods for solving the inviscid and boundary-layer flows are briefly described. The main objective of the investigation is the development of an interaction technique between both regions of flow. The method chosen for the …

Nonlinear Interfacial Waves in Inviscid Gas-Liquid Flows
This thesis is concerned with understanding and modeling the interfacial waves that exist in stratified gas-liquid flows. The motivation is the central role that interfacial waves are believed to play in flow regime transitions as well as their effect in critical design parameters.

Inviscid flow from a slot into a cross stream
… thesis describes a new method for predicting inviscid non-isoenergetic flow from an arbitrarily inclined slot into a uniform free stream. In the absence of flow separation the solution depends on three parameters: [i] the slot angle 13, [ii] a parameter, Cpt, describing the difference in total …

A new direct viscous-inviscid interaction method for aerodynamics analysis
… Such approach is known as the direct viscous–inviscid interaction (DVII) method. The Euler equation is solved by use of finite volume method based on Roe‟s cell center Scheme while the Boundary layer equation is solved by use of the Keller Box method. Firstly the flow problem is solved which …

Application of viscous-inviscid interaction methods to transonic turbulent flows
<p>Two different viscous-inviscid interaction schemes have been developed for the analysis of steady transonic flows. The viscous and inviscid solutions are coupled through the displacement concept using a transpiration velocity. In the semi-inverse interaction method, the viscous and inviscid …

Blow-up of Solutions to the Generalized Inviscid Proudman-Johnson Equation
<p>The generalized inviscid Proudman-Johnson equation serves as a model for n-dimensional incompressible Euler flow, gas dynamics, high-frequency waves in shallow waters, and orientation of waves in a massive director field of a nematic liquid crystal. Furthermore, the equation also serves as a …

Nonlinear wave modulation in an inviscid and viscous fluids-filled thin viscoelastic tube
… By considering the blood as an incompressible inviscid fluid and viscous fluid, two mathematical models of nonlinear wave modulation in thin viscoelastic tube are formed through the use of the reductive perturbation method. The equation of fluids used in this research are exact equations where …

One-Dimensional Flow Properties for a Specified Dissociation Variation of an Inviscid Diatomic Gas
… equations for the one-dimensional flow of an inviscid dissociating diatomic gas have been solved numerically for a specified concentration variation. The results indicated that certain restrictions must be made on the input concentration functions in order to obtain physically meaningful …

An anisotropic adaptive method for the solution of 3-D inviscid and viscous compressible flows
… developed for the solution of three-dimensional inviscid and viscous flows by the finite element method. An edge-based error estimate drives a mesh movement strategy that allows directional stretching and re-orientation of the grid with more mesh points introduced along those directions with …
