The optimal hydraulic diameter of semicircular and triangular shaped channels for compact heat exchangers
(North-West University, 2010)All heat pump cycles have one common feature that connects them to one another; this feature is the presence of a heat exchanger. There are even some heat–driven cycles that are completely composed of heat exchangers, every ... -
Performance predictions for oil contaminated supercritical carbon dioxide gas cooling
(North-West University (South Africa), 2019)The international movement towards using natural refrigerants has resulted in the reinvestigation of trans-critical heat pump cycles using carbon dioxide. Subsequently, a need to predict the heat transfer of oil-contaminated ... -
A supercritical R-744 heat transfer simulation implementing various Nusselt number correlations
(North-West University, 2010)During the past decade research has shown that global warming may have disastrous effects on our planet. In order to limit the damage that the human race seems to be causing, it was acknowledged that substances with a high ...
