A numerical comparison of the thermal performance of different shapes of corrugated channels as well as straight channels in a turbulent flow of ZnO–water nanofluid under constant heat flux was investigated. The finite volume method with the SIMPLE technique was employed to solve the governing equations. Different forms of corrugated channels, including trapezoidal, house-shaped, and semicircle channels, were tested using nanoparticles volume fractions and Reynolds number ranging from 0 to 0.08 and 10,000 to 30,000, respectively. Heat transfer, pressure drop, streamwise velocity contours, temperature contours, and thermal performance were found and analyzed. The simulation outcomes indicated that the performance of the corrugated channels was extremely affected by corrugation shape. For the channel shapes under consideration, the heat transfer and pressure drop increased when the nanoparticles volume fraction and Reynolds number increased. The trapezoidal channel has the best thermal performance followed by the semicircle and house-shaped channels.
