Introduction Standing hundreds of meters above the ground, modern wind turbines have become one of the most recognizable symbols of renewable energy. Despite decades of technological advancement, one design feature has remained remarkably consistent: almost every utility-scale wind turbine has three blades. This raises an interesting engineering question—if more blades capture more wind, why […]
Introduction The flow around bluff bodies, particularly circular cylinders, is a fundamental topic in fluid mechanics due to its importance in engineering applications such as heat exchangers, offshore structures, bridge piers, chimneys, and tube banks. When fluid flows past a circular cylinder, the boundary layer separates from the surface because of an adverse pressure gradient,
Introduction Renewable energy has become increasingly important due to the growing demand for clean and sustainable power sources. Wind energy is one of the most widely used renewable energy resources because it is environmentally friendly and readily available. A Vertical Axis Wind Turbine (VAWT) converts the kinetic energy of wind into mechanical and electrical energy.
Introduction Fluid mechanics is a basic engineering discipline that is concerned with the study of fluids in motion and at rest. Knowing how air flows around objects is critical in the design and analysis of aircraft, cars, wind turbines, buildings, bridges, and many other engineering systems. A wind tunnel is one of the best experimental
Introduction Flow visualization is one of the most important experimental techniques in fluid mechanics, as it helps to understand the behavior of fluid flow around different objects. It allows engineers and researchers to observe streamlines, flow separation, wake formation, and vortex structures that cannot be seen with the naked eye. Commercial water channels used for
