RK4 integrator, projection selectable, color by time/speed/z. Try classic σ=10, ρ=28, β=8/3.
The Lorenz Attractor is a set of solutions to a simplified system of differential equations that model convection in fluids, first proposed by mathematician Edward Lorenz. These solutions form a complex, looping pattern, often referred to as a “butterfly” or “figure eight” shape, which is visually captivating. The Lorenz Attractor is a prime example of a chaotic system, where small changes in initial conditions can result in vastly different outcomes—a phenomenon known as the “butterfly effect.” This attractor is significant in the field of chaos theory and has been extensively studied to gain insights into the behavior of complex systems.
In the context of the Lorenz system, which is a mathematical model of atmospheric convection, σ (sigma), ρ (rho), and β (beta) are crucial dimensionless parameters that govern the system’s chaotic behavior. Here’s a breakdown of what each parameter represents:
σ (Sigma): Prandtl Number: This parameter relates the kinematic viscosity of the fluid to its thermal diffusivity. It essentially indicates how quickly momentum diffuses compared to heat in the fluid.
ρ (Rho): Rayleigh Number: This parameter signifies the strength of the external forcing or the temperature difference across the fluid layer. A higher Rayleigh number implies stronger convection. The onset of instability and chaotic behavior in the Lorenz system is related to the value of ρ.
β (Beta): Dimension Parameter: This parameter represents the physical dimensions of the fluid layer itself. Specifically, it relates the aspect ratio of the fluid layer, influencing the geometry of the convection cells formed.
