Journal ArticleDOI
Investigating the efficacy of nanofluids as coolants in plate heat exchangers (phe)
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.
Journal ArticleDOI

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.
Journal ArticleDOI
Effect of liquid properties on the performance of bubble column reactors with fine pore spargers
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.
Journal ArticleDOI
Experimental study of bubble formation at metal porous spargers: Effect of liquid properties and sparger characteristics on the initial bubble size distribution
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.
Journal ArticleDOI
Statistical characteristics of free falling films at high reynolds numbers
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.
