Conjugate heat transfer analysis of double pane windows

Analysis of the conjugate heat transfer in a multi-layer wall including an air layer

“…In order to understand this problem, a previous study of the conjugate heat transfer was made of a multi-layer wall (Balderas et al, 2007), where it was observed that a critical thickness exists which identified the beginning of the natural convection process in the air layer. This same result was obtained by Aydin (Aydin, 2006) in the analysis of the conjugate heat transfer through a double pane window, where the effect of the climatic conditions was studied. For the analysis of the multi-layer wall a model applying the volume finite method (Patankar, 1980) was developed.…”

“…This concept is applied in the insulating of enclosures or spaces constructed with perforated bricks to maintain the comfort, without using additional thermal insulator in the walls (Lacarrière et al, 2003;Lacarrière et al, 2006). Besides it has been used to increase the insulating effect in the windows of the enclosures (Aydin, 2000;Aydin, 2006). Nevertheless, the thickness of the air layer must be such that it does not allow the movement of the air.…”

Conjugate natural convection in the roof cavity of heavy construction building during summer

“…For example, Manz [1] investigated natural convection of air layers within vertical, rectangular cavities in relation to applications in building facade elements, such as insulating glazing units, double-skin facades, and doors. Al-Hazmy [2] analyzed the coupled convective and conduction heat transport mode in a common hollow building brick, and Aydın [3] studied conjugate heat transfer through a double pane window.…”

A second-order time-accurate finite element method for analysis of conjugate heat transfer between solid and unsteady viscous flow

“…Schäfer and Teschauer [11] used the finite volume method to analyze both the fluid flow behavior and the solid heat transfer together. Aydin [12] studied a conjugate heat transfer phenomenon through a double pane window by using the finite difference technique. Results from these problems showed that both the finite difference and the finite volume methods can perform very well on the problems of interest, but some assumptions on heat transfer coefficients have to be made in order to compute the temperatures along the fluid-solid interface.…”
