Transonic viscous inviscid interactions in a slender Laval nozzle

Quasi-Simultaneous Viscous-Inviscid Interaction for Transonic Airfoil Flow

Following Prandtl, a viscous-inviscid interaction (VII) method is presented, where the flow field is divided into a viscous shear layer and an inviscid outer region. Their coupling is performed with the quasi-simultaneous approach, making use of an appropriately chosen interaction law. Firstly, an engineering example of transonic airfoil flow is presented, in which the interaction law is based ...

Application of viscous-inviscid interaction methods to transonic turbulent flows

Inviscid and Viscous Interactions in Subsonic Corner Flows

A flap can be used as a high-lift device, in which a downward deflection results in a gain in lift at a given geometric angle of attack. To characterize the aerodynamic performance of a deflected surface in compressible flows, the present study examines a naturally developed turbulent boundary layer past the convex and concave corners. This investigation involves the analysis of mean and fluctu...

Linear stability of the sub-to-super inviscid transonic stationary wave for gas flow in a nozzle of varying area

In this work we consider the linear stability of a sub-to-super inviscid transonic stationary wave of a one-dimensional model of isentropic compressible flows through a nozzle of varying area. This sub-to-super inviscid transonic stationary wave is newly founded by the authors using the geometric singular perturbation theory. The main result of this work is to show that the sub-to-super invisci...
