TL;DR: In this paper, the efficacy of nanofluids as coolants is investigated in industrial heat exchangers, where large volumes of nano-fluids are necessary and turbulent flow is usually developed.

TL;DR: In this paper, the effect of the use of a nanofluid in a miniature plate heat exchanger (PHE) with modulated surface has been studied both experimentally and numerically.

TL;DR: In this article, the effect of liquid properties on the performance of bubble column reactors with fine pore spargers was studied. But the authors focused on the effect on the average gas holdup values, bubble size distributions and Sauter diameters and were consistent with existing physical models on coalescence/breakage.

TL;DR: In this article, the effect of liquid properties and pore size on the initial bubble size distribution of a bubble column equipped with a fine pore sparger was studied, and a new correlation regarding the prediction of the initial mean Sauter diameter of bubbles formed from porous spargers at the homogeneous regime was formulated and found to be in good agreement with available data.

TL;DR: In this article, the characteristics of films flowing inside a vertical pipe are studied experimentally using an accurate wire conductance technique, and the mean film thickness is measured over the Re range 509-13,090.
