Benefits Derivable from Connecting the Bottom and Top Walls of Attic Enclosures with Insulated Vertical Side Walls

Finite element analysis of natural convection in a triangular enclosure: Effects of various thermal boundary conditions

“…A few recent studies on natural convection in triangular enclosures have also been carried out for various applications (Varol et al, 2006;Ridouane et al, 2006;Tzeng et al, 2005;Joudi et al, 2004). Joudi et al (2004) studied numerically, the performance of a prism shaped solar collector with a rightangled triangular cross-sectional area.…”

“…It is found that the location of heater plays a significant role on flows and heat transfer rates within the enclosure. Ridouane et al (2006) studied natural convection within attic spaces of houses and buildings with sloped roofs and horizontally suspended ceilings. The efficient heating strategies have been proposed for various seasons.…”

Natural convection in a triangle enclosure with flush mounted heater on the wall

“…Varol et al [14], Wang [15], Kim et al [16], Wintruff [17], and Ridouane [18] made studies on natural convection in corrugated enclosures using different numerical techniques.…”

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

“…Heat-flow in building attic spaces was numerically investigated by several researchers [4][5][6][7][8][9][10][11][12][13][14]. For example, Akinsete and Coleman [4] numerically investigated twodimensional laminar free convection in air contained in a long horizontal right-triangular enclosure for height-base ratios of 0.0625-1.0 and Grashof number (Gr) of 800-64,000.…”

“…For the Gr range considered, velocity and temperature results were stable for the first case while non-symmetrical flow structure was produced for the second case. Ridouane et al [14] studied buoyant air circulation inside trapezoidal attic spaces formed by adding heavily insulated, vertical side walls at the hot/cold intersection between the active walls of originally isosceles triangular enclosure. They concluded that the presence of insulated sidewalls, even of very small height, provides a huge gain of energy during cooling and heating seasons.…”
