Richard Edward Arnold (May 15, 1918 – May 8, 2008) was an influential American country music singer, renowned for his pioneering work in the Nashville sound movement of the late 1950s. His impact on the country music scene is evident through his remarkable achievement of scoring 147 songs on the Billboard country music charts, earning him the second spot, just behind the legendary George Jones. Arnold's contribution to the music industry is exemplified by his impressive record sales, surpassing 85 million. He was honored with memberships in esteemed institutions such as the Grand Ole Opry and the Country Music Hall of Fame, solidifying his status as a country music icon. Notably, Arnold was ranked 22nd on Country Music Television's prestigious list of "The 40 Greatest Men of Country Music" in 2003. His journey to stardom began on a farm near Henderson, Tennessee, where he developed a passion for music, taught by his musical parents. Despite facing adversity following his father's untimely passing, Arnold persevered and honed his musical talents, earning the moniker "the Tennessee Plowboy." His career took off with a series of notable performances on various radio stations, ultimately leading to a groundbreaking contract with RCA Victor. Arnold's impact extended beyond his musical prowess, as he ventured into television, hosting successful programs that further elevated his prominence in the industry.

In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void, creating a swirl of fluid on each edge of the obstacle, followed by a short reverse flow of fluid behind the obstacle flowing upstream, toward the back of the obstacle. An eddy is a movement of fluid that deviates from the general flow of the fluid. An example of an eddy is a vortex which produces such deviation. However, there are other types of eddies that are not simple vortices. In 1883, scientist Osborne Reynolds conducted a fluid dynamics experiment involving water and dye, where he adjusted the velocities of the fluids and observed the transition from laminar to turbulent flow, characterized by the formation of eddies and vortices. Turbulent flow is defined as the flow in which the system's inertial forces are dominant over the viscous forces. This phenomenon is described by Reynolds number, a unit-less number used to determine when turbulent flow will occur. In terms of the critical Reynolds number, the critical velocity is represented as vc = Recμ/ρd. These are turbulence models in which the Reynolds stresses, as obtained from a Reynolds averaging of the Navier–Stokes equations, are modeled by a linear constitutive relationship with the mean flow straining field.
