The impact of sonication and stirring durations on the thermal conductivity of alumina-liquid paraffin nanofluid: An experimental assessment
TL;DR: In this paper, the impact of the duration of various stages of nanofluid preparation on its thermal conductivity was investigated and it was found that the optimal sonication time is 3'h and 15min, and a further intensification in this time breaks the bond between the nanoadditives and the surfactant, resulting in less thermal conductivities.

Numerical study on geometrical specifications and operational parameters of multi-tube heat storage systems
TL;DR: In this article, the effect of number of tubes as well as their arrangement as geometrical parameters on liquid fraction, phase front and melting time was studied. And the results also showed that the ones whose tubes are located within the upper half of the shell are candidates for the longest melting time.
