Calculating Window Solar Heat Gain
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-07)
Window design has been revolutionized-largely by the introduction of low emissivity (low-e) coatings and substitute fill gases. The large number of design options necessitates the use of computer simulation for development ...
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 ...
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 ...
Flow visualization of natural convection in a tall, air-filled vertical cavity
(Elsevier, 2006-03-01)
Natural convection of air in a tall vertical cavity was studied using a smoke patterns and interferometry. Experiments covered Rayleigh numbers of 4850 < Ra < 54,800 and aspect ratio A ≈ 40. Secondary cells were noted at ...
Asymmetric Graetz Problem: The Analytical Solution Revisited
(American Institute of Aeronautics and Astronautics, 2017-01-01)
Forced-convective heat transfer from the walls of an asymmetrically heated channel to the fluid passing through in a laminar, hydrodynamically developed flow is known as the asymmetric Graetz problem. Several analytical ...
Laminar Free Convection from a Pair of Horizontal Cylinders: A Three-Temperature Problem
(2015-06)
The formulation of multi-temperature convection problems in terms of a single driving temperature difference and a single heat transfer coefficient does not properly reflect the physics of the problem. Paired heat transfer ...
A Study Of Pane Spacing In Glazing Systems
(Solar Energy Society of Canada, 1989-06)
The selection of optimum pane spacing for glazing systems has been a topic of ongoing debate in the window manufacturing industry. Arguments are often based on speculation, intuition and results from tests not specifically ...
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 ...
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 ...
A method for determining the effective longwave radiative properties of pleated draperies
(Taylor & Francis, 2011-10-01)
Draperies, attached to fenestration, offer a cost-effective strategy in controlling solar gain since draperies have the potential to reduce building peak load and annual energy consumption. The performance of a drapery is ...
