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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
