Numerical Comparison of Cu and Al\(_2\) O\(_3\) Nanoparticles in an MHD Water-based Nanofluid. Journal of Engineering Research and Reports, 26(6), 139-146.https://doi.org/10.9734/jerr%2F2024%2Fv26i61168https://ir-library.ku.ac.ke/handle/123456789/28330ArticleIn this study, the impact of 𝐶𝑢 and 𝐴𝑙2𝑂3 nanoparticles in a water-based nanofluid are considered. The application of this can be found in biomedical sensors and drug delivery. Specifically, it investigates heat transfer in the MHD flow of two nanofluids (𝐶𝑢-water and 𝐴𝑙₂𝑂₃-water) over an exponentially stretching surface. The study formulates a model and renders it dimensionless using Similarity Transformation. Numerical solutions are obtained using the MATLAB package bvp4c. The focus is on analysing the heat transfer rate variation with nanoparticle volume fraction. Results indicate that 𝐶𝑢-water nanofluid exhibits higher heat transfer rates and lower skin frictions compared to 𝐴𝑙₂𝑂₃-water nanofluid.enHeat transferMHD flowhybrid nanofluidArticle
