.... It is theorized that this interaction leads to an increase in the viscosity of the fluid, which is not present when either additive alone is used. The impact decreases with temperature, and is most noticeable right around the melt temperature of the PCM, which means the viscosity increase may have an impact...

...Loong-Ee Loh; Jie Song; Fenglin Guo; Guijun Bi Selective laser melting (SLM) has received increasing attention in recent years as an innovative manufacturing technique. The present SLM process only uses a single laser beam to melt and consolidate the powder, which may result in excessive...

The results show that for all the heat flux distributions, the slight clockwise rotation of the cavity can accelerate the melting process. Furthermore, when more heat...

... time, the use of a high loading (e.g., 3.0 wt %) was demonstrated to be possibly uneconomical because of the marginal gain in heat retrieval rate. Finally, correlations for the transient variations of the melt fraction and surface-averaged Nusselt number were proposed. 1 These authors contributed...
