Numerical Investigation on the Influence of Protrusion Height on Heat Transfer and Fluid Flow within Rectangular Channel with Nanofluid

This study focuses on investigating the impact of using Aluminium Oxide (Al2O3) nanofluid on heat transfer within a rectangular channel featuring different protrusion heights. The primary objectives include analysing fluid flow characteristics and heat transfer performance in the channel and determining the optimal parameters and specifications. Additionally, this study places emphasis on examining the influence of protrusion height on fluid flow and heat transfer in conjunction with nanofluids. The obtained numerical results are compared with other relevant findings. The findings reveal a positive correlation between the heat transfer coefficient and both the protrusion height and Reynolds number. Similarly, the Nusselt number demonstrates an increase with the protrusion height. Furthermore, the friction coefficient displays a slight increase with both the protrusion height and Reynolds number, although the differences are not statistically significant.
