COMBINED EFFECT OF OBLIQUE RIBS AND A NANOFLUID ON THE THERMAL-HYDRAULIC PERFORMANCE OF A CORRUGATED CHANNEL: NUMERICAL STUDY

The thermal-hydraulic performance of a ribbed corrugated channel in which a hybrid nanofl uid fl ows was numerically investigated in the wide range of change in the Reynolds number of the fl uid fl ow 5000–25,000 with the use of the k–ε model of turbulence. Rectangular oblique ribs diff erent in geometry were considered, and a CuO/MgO–water nanofl uid was used as a working fl uid. It was established that the corrugations and the oblique ribs in such a channel aid in increasing the heat transfer in it, and the CuO/MgO particles in the base fl uid improve its thermophysical properties and, hence, the thermal performance of the system.
