    Tri-hybrid nanoparticle effect on non-Newtonian fluid flow over vertical heated surface
    (UMT Lahore, 2023-09-22) Muhammad Haris Butt
    This thesis presents the expansion of an analytical model for the performance of Oldroyd-B nanofluid, where ethylene glycol is assumed as the base fluid and copper (Cu) tri-nanoparticles are introduced for nanofluid preparation. A systematic strategy is established by converting the related nonlinear governing equations into dimensionless form. To find analytical solutions for the research problem, the Laplace transformation is used as a key tool. This research includes a review of the effects of important variables on the temperature and velocity patterns inside the fluid. In particular, the temperature shows an upward trend with increasing nanoparticle volume fraction parameters (φ1, φ2, φ3), whereas it shows a downward trend with increasing Prandtl number (Pr) values. In providing precise answers, the Laplace transformation has proven to be effective and useful for a variety of heat transport problems, particularly those involving composite geometry. Comparative analysis is done by comparing the obtained results to those produced by the mathematical software Mathcad.
