The text provides insight into the different mathematical tools and techniques that can be applied to the analysis and numerical computations of flow models. It further discusses important topics such as the heat transfer effect on boundary layer flow, modeling of flows through porous media, anisotropic polytrophic gas model, and thermal instability in viscoelastic fluids.This book:Discusses modeling of Rayleigh-Taylor instability in nanofluid layer and thermal instability in viscoelastic fluidsCovers open FOAM simulation of free surface problems, and anisotropic polytrophic gas modelHighlights the Sensitivity Analysis in Aerospace Engineering, MHD Flow of a Micropolar Hybrid Nanofluid, and IoT-Enabled Monitoring for Natural ConvectionPresents thermal behavior of nanofluid in complex geometries and heat transfer effect on Boundary layer flowExplains natural convection heat transfer in non-Newtonian fluids and homotropy series solution of the boundary layer flowIllustrates modeling of flows through porous media and investigates Shock-driven Richtmyer-Meshkov instabilityIt is primarily written for senior undergraduate, graduate students, and academic researchers in the fields of Applied Sciences, Mechanical Engineering, Manufacturing Engineering, Production Engineering, Industrial engineering, Automotive engineering, and Aerospace engineering.
