Wave and Turbulent Film Condensation on a Vertical Surface. Correlation for Local Heat-Transfer Coefficient.

Analysis of Laminar Film Condensation on a Vertical Plate

Laminar Film Condensation Heat Transfer on a Vertical, Non-Isothermal, Semi- Infinite Plate

This paper gives similarity transformations for laminar film condensation on a vertical flat plate with variable temperature distribution and finds analytical solutions for arbitrary Prandtl numbers and condensation rates. The work contrasts with Sparrow and Gregg’s assertion that wall temperature variation does not permit similarity solutions. To resolve the long debatable issue regarding heat...

Heat Transfer under Double Turbulent Pulsating Jets Impinging on a Flat Surface

In this study, the numerical analysis of turbulent flow and heat transfer of double pulsating impinging jets on a flat surface has been investigated. The unsteady two-dimensional numerical solution for two similar and dissimilar jets was performed using the RNG k-ε model. The results showed that the RNG k-ε model has more satisfactory predictions of the Nusselt number distribution. Comparisons ...

Influence of Non-Uniform Wall Temperature on Local Heat Transfer Coefficient in a Rotating Square Channel

 Abstract: This paper presents the results of an experimental examination of the effect of non-uniform wall temperature on local heat transfer coefficient in a rotating smooth-walled square channel. Three different thermal boundary situations were investigated: (a) even and odd (four) wall uniform temperature, (b) even and odd (four) wall uniform heat flux, and (c) even (leading and trailing) w...

Unsteady Heat and Mass Transfer Near the Stagnation-point on a Vertical Permeable Surface: a Comprehensive Report of Dual Solutions

In this paper, the problem of unsteady mixed convection boundary layer flow of a viscous incompressible fluid near the stagnation-point on a vertical permeable plate with both cases of prescribed wall temperature and prescribed wall heat flux is investigated numerically. Here, both assisting and opposing buoyancy forces are considered and studied. The non-linear coupled partial differential equ...
