TLDR
In this article, the stability of boundary layer free convection from an inclined plane surface has been investigated, and the relative contributions of hydrodynamic and thermal effects are investigated, showing that thermal effects through surface inclinations are increasingly significant as the surface departs further from the vertical position and that positive and negative inclinations do not produce equal and opposite effects.Abstract:
The results of an experimental study of the stability of boundary layer free convection from an inclined plane surface are presented. In particular, the relative contributions of hydrodynamic and thermal effects are investigated. It is demonstrated that thermal effects, through surface inclinations, are increasingly significant as the surface departs further from the vertical position and that positive and negative inclinations do not produce equal and opposite effects.read more

A General Method of Obtaining Approximate Solutions to Laminar and Turbulent Free Convection Problems
G. D. Raithby,K.G.T. Hollands +1 more
TL;DR: In this paper, the authors focus on determining equations for the local and mean rate of laminar heat transfer, which are approximately valid for different geometries by use of these equations, several new correlations are obtained for various heat transfer problems, and the results compared with experiments.

TL;DR: In this paper, the relationship between the nature of flow instability and the inclination angle of the plate was established, and the angular dependence of the Rayleigh number characterizing the onset of instability was also determined.

On the stability of natural convection boundary layer flow over horizontal and slightly inclined surfaces
L Pera,Benjamin Gebhart +1 more
TL;DR: In this paper, the stability of a natural convection boundary layer flow adjacent to horizontal and to slightly inclined surfaces was analyzed using a Mach-Zehnder interferometer, and the results of a perturbation analysis of such flows were used to study flow characteristics under both disturbed and undisturbed conditions.

Tiebing Chen,Aleksandros Mucoglu +1 more
TL;DR: In this article, the linear wave instability of laminar mixed convective flow over an isothermal horizontal flat plate is studied analytically, and the main flow and thermal fields employed in the stability analysis are treated as non-parallel.

On the Stability for Three-Dimensional Disturbances of Viscous Fluid Flow between Parallel Walls
TL;DR: In this article, it was shown that the breakdown of laminar flow depended primarily on the size of the initial disturbance, in agreement with the Reynold's view, and that the reoughness of the walls might not be the determining factor.

Thermal instability in a horizontal fluid layer: effect of boundary conditions and non-linear temperature profile
TL;DR: In this article, the authors investigated the conditions marking the onset of convective motion in a horizontal fluid layer, in which a negative temperature gradient occurs somewhere within the layer, and they found that the Rayleigh number is greatest for the boundary conditions of fixed temperature and decreases monotonically as the condition of fixed heat flux is approached.

Some Cases of Instability in Fluid Motion
TL;DR: In this paper, the authors obtained a numerical solution of some problems concerning the stability of a layer of incompressible fluid when the temperature decreases upwards, and the results depended on the solution of the sixth-order differential equation (d 2/d ζ2 -a 2)3 Z = -λ a 2Z.
