Numerical Simulation of Low Reynolds Number Incompressible Flow over Two Side-by-Side Circular Cylinders
Abstract: A second-order accurate unstructured collocated implicit finite volume method based on the primitive-variable formulation is used to study the flow field around a pair of cylinders arranged in side-by-side configuration. Numerical simulations are carried out for long time on a high-resolution mesh to obtain the appropriate evolution of the overall flow field and vortex structure of the wakes. A wide range of gaps between the cylinders is considered over a …

Vortex-Induced Vibration of a Circular Cylinder at Low and Subcritical Reynolds Numbers-Part I: Low Reynolds Numbers
Abstract: The vortex-induced vibration of a circular cylinder at low and low subcritical Reynolds numbers is studied numerically over wide ranges of the influencing parameters. The cylinder dynamics is modeled using a spring-damper-mass system and the fluid dynamics is simulated using the two-dimensional approximation. An implicit, collocated moving grid finite volume algorithm implemented on an unstructured triangular mesh is adopted to solve the fluid dynamic equations. The numerical simulation confirms that …

Hydrodynamic Analysis of Symmetrical Naca Airfoils: A CFD Simulation Approach
Abstract: This study presents a comprehensive numerical investigation of the hydrodynamic characteristics of selected NACA airfoil profiles using advanced computational fluid dynamics (CFD) simulations performed in ANSYS Fluent. The primary objective is to evaluate the fluid–structure interaction behavior of these airfoils when subjected to marine flow conditions relevant to offshore and submerged engineering applications. By modeling the interaction between incompressible fluid flow and various NACA geometries, the study systematically analyzes key …

Comparative CFD Analysis of Major and Minor Aerodynamic Modifications for Tall Building Shapes under Wind Loading
Abstract: Aerodynamic performance of tall buildings is significant to structural safety and serviceability under wind. The major and minor aerodynamic changes of the tall building shape are compared with the computational fluid dynamics (CFD) simulation. The base model was a rectangle of 75 m × 75 m × 300 m. Various aerodynamic modifications of shapes were examined: circular, elliptical, tapered, twisted, rounded-corner, and chamfered-corner shapes. Simulations were carried out in the …

Effect of Blunt Truncation in an Aerospike Nozzle
Abstract: Aerospike nozzles are gaining attention as a more advanced alternative to conventional bell nozzles, mainly because they can perform efficiently across a wide range of altitude conditions. Unlike traditional converging–diverging nozzles, aerospike designs naturally adjust to changes in ambient pressure, allowing the exhaust flow to expand more effectively. This results in better thrust performance under varying operating conditions, making them a strong candidate for future aerospace propulsion systems. In this …

Graphene-Derived Reinforced Polymer Composites for Self-Healing and Durability Enhancement in Concrete Structures
Abstract: This study presents a matrix-centric polymer-composite repair binder: an epoxy–polyamide network reinforced with graphene derivatives (GO/rGO, 0.1–1.0 wt%). The polymer drives function via segmental mobility that closes microcracks, while 2D-filler topology densifies the interphase, improves load transfer, and enforces tortuous moisture pathways. Adhesion was high: pull-off (ASTM D4541) reached 13.5 MPa at 2.0 mm displacement; slant-shear (ASTM C882) reached 12.1 MPa at 2.8 mm, with greater deformation capacity (zero stress …

Numerical Investigation of Influence of Rate of Rotation on Formation of Vapor Around Two Heated Circular Cylinders Immersed in Water Inside a Channel
Abstract: AbstractThe complexity problem of fluid flow and heat transfer over an array of circular cylinders are common in industrial applications of the fluid dynamics. The complex nature of the problem encountered in industry, gives rise to certain significant dimensions in the fluid dynamics theory. Some of them are the fluid flow interaction, interferences in flow and vortex dynamics which are typically found in compact heat exchangers, cooling of electronic equipment, …

Groundwater Potential, Status and Its Recharge Behavior under Climate Change Consequence
Abstract: Water is considered life for every living substance, from simple ones to complex structural systems that exist on the earth. Without water, life is not possible. The only source of water is precipitation and it is uncertain in a country like India, where demand for water is increasing at a tremendous rate in each and every sector. To satisfy this increasing demand of water in each and every sector, one …
