A Computational Study of Lift and Drag Characteristics for NACA 4415 and NACA 2412 Aerofoils
Abstract: The performance of an aerofoil is crucial in designing wind turbine blades, aircraft wings, and other aerodynamic surfaces. This project presents a comparative analysis of two widely used aerofoil profiles, NACA 4415 and NACA 2412, to study their lift and drag characteristics under different flow regimes. The aerofoil geometries were developed using the NACA four-digit notation and modeled in ANSYS Design Modeler. Numerical simulations were conducted in ANSYS Fluent for …

Influence of Horizontal Crossflow on the Rayleigh-Taylor Instability: A Numerical Approach
Abstract: Rayleigh-Taylor Instability (RTI) is a typical occurrence in natural events, engineering, and industrial applications. When the lighter fluid (bottom medium) is forcing the heavier fluid (top medium) on top of the lighter fluid because of a gravitational field, then that phenomenon is called Rayleigh-Taylor instability (RTI). Despite extensive records of investigating this common phenomenon i.e., RTI with several unique boundary conditions, apparently, there are no prior investigations for the RTI …

Investigation of Forced Convection Heat Transfer Efficiency Using Cuo/Water Nanofluid in A Concentric Tube Heat Exchanger with Helical Coiled Insert
Abstract: An apparatus that uses nanofluid to transport heat is called a heat exchanger. This uses a nanofluid as the working fluid. One can make nanofluid hanging nanoparticles in liquids such as petroleum products, water, oil, ethylene glycol, fluorocarbons, etc. Forced convection heat transfer using CuO/water as a Nanofluid and distilled water as the base fluid has been examined in a concentric tube heat exchanger with helical coiled insert. Tests on …
