TL;DR: In this paper, a mechanistic model for wall heat flux partitioning during subcooled flow boiling was proposed and validated using experimental data obtained as part of the validation process, and the developed model was applied to experimental data.
Abstract: A mechanistic model for wall heat flux partitioning during subcooled flow boiling proposed in Part I of this two-part paper, is validated in this part. As the first step of the validation process, the developed model was applied to experimental data obtained as part of this study

TL;DR: In this paper, the effect of condenser subcooling on the performance of an air conditioning system operating with R134a and R1234yf, under the same operating conditions was investigated.
Abstract: This paper presents an experimental study about the effect of condenser subcooling on the performance of an air conditioning system operating with R134a and R1234yf, under the same operating conditions For both refrigerants, it has been shown that the COP undergoes a maximum as a consequence of the trade-off between increasing refrigerating effect and increasing specific compression work At a given operating condition, the system COP increased up to 18% for R1234yf and 9% for R134a These results confirmed the trends obtained from a previous theoretical analysis, demonstrating that a system operating with R1234yf can benefit more from the condenser subcooling than that with R134a The experimental results also showed that the presence of an internal heat exchanger significantly reduces the COP increase due to condenser subcooling, since both improvements compete towards reducing the throttling losses Besides the interference between IHX and condenser subcooling, the use of both simultaneously still yields a more efficient air conditioning system, especially for R1234yf

TL;DR: In this paper, heat transfer on super-hydrophobic Si nanowire (SiNW) array-coated surface was investigated and it was shown that SHB surface could have a superior heat and mass transfer performance than hydrophobic surface provided that the liquid droplets on the SHB could be shed away efficiently.

TL;DR: In this article, two models of heat transfer through the heating foil and the isolating glass into the boiling liquid were proposed and discussed: one-and two-dimensional heat conduction problems were used with application of the least square and Trefftz computational techniques.
