Asymmetrical non-uniform heat flux distributions for laminar flow heat transfer with mixed convection in a horizontal circular tube

Okafor, Izuchukwu F.; Dirker, Jaco; Meyer, Josua P. (Taylor and Francis, 2019)

Non-symmetric heat flux distributions in terms of gravity in solar collector tubes influence buoyancy-driven secondary flow which has an impact on the associated heat transfer and pressure drop performance. In this study ...
Influence of circumferential solar heat flux distribution on the heat transfer coefficients of linear Fresnel collector absorber tubes

Okafor, Izuchukwu F.; Dirker, Jaco; Meyer, Josua P. (Elsevier, 2014-09)

The absorber tubes of solar thermal collectors have enormous influence on the performance of the solar collector systems. In this numerical study, the influence of circumferential uniform and non-uniform solar heat flux ...
Influence of non-uniform heat flux distributions on the secondary flow, convective heat transfer and friction factors for a parabolic trough solar collector type absorber tube

Okafor, Izuchukwu F.; Dirker, Jaco; Meyer, Josua P. (Elsevier, 2017-08)

Non-uniform heat flux profiles on circular tubes are found in a number of heat transfer applications, including solar heating. In this numerical study the influence of the circumferential angle spans of non-uniform heat ...
Laminar flow heat transfer for asymmetrical non-uniform heat flux distributions on horizontal circular tubes

Okafor, Izuchukwu F.; Dirker, Jaco; Meyer, Josua P. (3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015., 2015)
