(AIP Publishing, 1981)
Görtler instability for boundary‐layer flows over generally curved walls is considered. The full‐linearized disturbance equations are obtained in an orthogonal curvilinear coordinate system. A perturbation procedure to ...
Effect of Bulges on the Stability of Boundary Layers
(AIP Publishing, 1988-04-01)
The instability of flows around hump and dip imperfections is investigated. The mean flow is calculated using interacting boundary layers, thereby accounting for viscous/inviscid interaction and separation bubbles. Then, ...
Exact Solutions for Sonic Shocks in Van Der Waals Gases
(AIP Publishing, 1987-02-01)
Exact closed-form solutions for finite amplitude sonic shocks are presented for the case of a van der Waals gas having a constant specific heat. Solutions are provided for both single and double sonic shocks. Sample ...
Flux formulation of hyperbolic heat conduction
(American Institute of Physics, 1985)
The development of the general flux formulation for heat conduction based on the modified Fourier's law is presented. This new formulation produces a hyperbolic vector equation in heat flux which is more convenient to use ...
Heat Transfer in a Rarefied Gas Enclosed Between Parallel Plates: Role of Boundary Conditions
(AIP Publishing, 1982)
The influence of boundary conditions of accomodation coefficients and Maxwellian diffuse specular reflection on heat transfer through a rarefied gas enclosed between two parallel plates is examined. An exact expression for ...
Influence of Streamwise Vortices on Tollmien-Schlichting Waves
(AIP Publishing, 1988-12-01)
An analysis is presented of the influence of steady quasiperiodic streamwise vortices on Tollmien-Schlichting (TS) waves. The vortices act as parametric exciters for the TS waves. The present analysis is for the subharmonic ...
Finding Straight Lines and Curves in Engineering Line Drawings

Neutral Stability Calculations for Boundary-Layer Flows
(AIP Publishing, 1980)
An analysis is presented of the parallel neutral stability of three‐dimensional incompressible, isothermal boundary‐layer flows. A Taylor‐series expansion of the dispersion relation is used to derive the general eigenvalues. ...
Globally Convergent Homotopy Methods: A Tutorial
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1987), TR-87-13
Secondary Instability of Plane Channel Flow to Subharmonic Three-Dimensional Disturbances
(AIP Publishing, 1983)
A linear secondary instability mechanism is presented that leads to the occurrence of subharmonic three‐dimensional disturbances in wall‐bounded shear flows. The instability originates from the periodic redistribution of ...
