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 nanofluid flows was numerically investigated in the wide range of change in the Reynolds number of the fluid flow 5000–25,000 with the use of the k–ε model of turbulence. Rectangular oblique ribs different in geometry were considered, and a CuO/ MgO–water nanofluid was used as a working fluid. 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 fluid improve its thermophysical properties and, hence, the thermal performance of the system
