The objectives of this study are to investigate the effect of chevron angle on heat transfer
performance in plate heat exchanger using lithium bromide solution and develop an
empirical correlation for Nusselt number prediction. Plate heat exchangers with chevron
angle of of 60 and 120 are tested in the present experiment. By varying the operational
conditions, the heat transfer performance is evaluated. The results reveal that heat transfer
rate, overall heat transfer coefficient and Nusselt number show 9%, 21% and 20% greater in …

The present experimental investigation focuses on the effect of symmetric (β∼ 30°/30° and
60°/60°) and mixed (β∼ 30°/60°) chevron angles in PHE on comparative energetic and
exergetic performance for nanofluid-water. The particle volume concentration of selected
ZnO/water nanofluid being used as coolant lies in range 0.5–2.0%. The experimental
findings elucidates the detailed observations of the effect of different chevron angles in PHE
on heat transfer rate ratio, heat transfer coefficient ratio, overall heat transfer coefficient ratio …
