Assessing Convective Heat Transfer Coefficients Associated with Indoor Shading Attachments Using a New Technique Based on Computational Fluid Dynamics
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2015-01)ASHRAE research project RP-1311 concluded with the creation of simulation models, the ASHWAT models, for glazing systems with shading attachments. Such assemblies are known as Complex Fenestration Systems (CFS). ASHWAT ... -
Convective Heat Transfer In Hydrodynamically-Developed Laminar Flow In Asymmetrically-Heated Annuli: A Three-Temperature Problem
(2016-07)Heat transfer in hydrodynamically-developed flow in asymmetrically-heated channels and annuli has been studied extensively. This study is an extension of earlier work where heat transfer in an asymmetrically-heated ... -
A Correlation to Quantify Convective Heat Transfer Between Vertical Window Glazings
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)Several correlations have been used in recent years for the purpose of calculating convective, centre-glass heat transfer rates across gas-filled interpane window cavities. These correlations are examined and their background ... -
Determination of convective heat transfer for fenestration with between-the-glass louvered shades
(Elsevier, 2008-06-01)In previous work, a two-dimensional steady laminar natural convection model of a window cavity with between-panes louvers (i.e., slats) was developed by approximating the system as a vertical cavity with isothermal walls ... -
Forced Convection From a Pair Of Spheres: A Three-Temperature Problem
(2015-05)Interaction of spherical particles in a fluid flow is important in combustion, chemical processes and air pollution. In this study, a recently developed technique for characterizing multi-temperature convective heat transfer ... -
Indoor-Side Convection Coefficients for Complex Fenestration Systems with Roller Blinds
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2017-01)In order to characterize the resistor network that describes convective heat transfer on the indoor side of a complex fenestration system, three convection coefficients are needed. Although methods to obtain convection ... -
Resistor-Network Formulation of Multi-Temperature Free Convection Problems
(American Institute of Aeronautics and Astronautics, 2017-01-11)In recent work, the resistor-network formulation of forced-convection problems and a technique (dQdT) for evaluating the paired convective resistances that characterize the network were presented. This technique entails ... -
Resistor-Network Formulation of Multitemperature Forced-Convection Problems
(American Institute of Aeronautics and Astronautics, 2016-09-07)Many convection heat transfer problems involve more than two isothermal heat sources/sinks. A network of multiple convective resistors connecting temperature nodes representing the isothermal sources (walls, inlet flows, ... -
Sensitivity of the Solar Heat Gain Coefficient of Complex Fenestration Systems to the Indoor Convection Coefficient
(International Building Performance Simulation Association, 2016)Accurate estimation of the solar gain of a fenestration system is important in analyzing the energy performance of buildings. Recently, models were developed for complex fenestration systems – glazing systems with attachments ... -
A Simplified Analysis of Radiant Heat Loss Through Projecting Fenestration Products
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2001)Current window analysis algorithms can deal with many features, including low-e coatings and substitute fill gases. These methods were developed for products with planar glazings. Results can be generated for projecting ...
