| dc.description.abstract | Window-windcatchers, a passive ventilation method, have been shown to improve ventilation and enhance thermal comfort. Preliminary characterization of a novel window-windcatcher has been undertaken in a previous work, but no relationship had been identified between the actual ventilation rate (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>Q</mi></mrow><mrow><mi>a</mi><mi>c</mi><mi>t</mi></mrow></msub></mrow></semantics></math></inline-formula>), the wind velocity (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>V</mi></mrow><mrow><mi>T</mi><mi>w</mi></mrow></msub></mrow></semantics></math></inline-formula>) and crucial design parameters such as the fins angle (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>ϴ</mi></mrow></semantics></math></inline-formula>)). In this paper, the relationship that quantifies how the window-windcatcher’s performance depends on <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>V</mi></mrow><mrow><mi>T</mi><mi>w</mi></mrow></msub></mrow></semantics></math></inline-formula> and <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>ϴ</mi></mrow></semantics></math></inline-formula> was determined. Additionally, for the first time, the ventilation performance of the window-windcatcher was optimized by studying the effects of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>ϴ</mi></mrow></semantics></math></inline-formula> and the fins-wall distance (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>D</mi></mrow><mrow><mi>W</mi><mo>−</mo><mi>f</mi></mrow></msub></mrow></semantics></math></inline-formula>) through a Computational Fluid Dynamics parametric study (ANSYS)|. In this optimization approach, the angle <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>ϴ</mi></mrow></semantics></math></inline-formula> and the distance <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>D</mi></mrow><mrow><mi>W</mi><mo>−</mo><mi>f</mi></mrow></msub></mrow></semantics></math></inline-formula> corresponding to the maximum actual-to-required ventilation rate were found to be 80° and 45 cm, respectively. The actual ventilation rate increased by approximately 13.2% compared with the baseline design of the windcatcher (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>ϴ</mi></mrow></semantics></math></inline-formula> and <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>D</mi></mrow><mrow><mi>W</mi><mo>−</mo><mi>f</mi></mrow></msub></mrow></semantics></math></inline-formula> equal to 40° and 45 cm, respectively); this corresponds to an increase of approximately 8.6% in the actual-to-required ventilation rate, according to the ASHRAE standards. | en |
