Chaos Theory and convergence in CFD simulation: a different approach in turbulence analysis

Starting form the beginning of 70’s chaos became not only a philosophical item but a brand new science touching nonlinear and the unpredictable phenomena. While most traditional science deals with supposedly predictable elements like gravity, electricity, or chemical reactions,

Chaos Theory deals with nonlinear phenomena that are effectively impossible to predict or control, like turbulence, thermofluid dyinamics or weather forecast. The complexity of chaotic dynamics like thermo-fluid dynamics will be investigated to understand how the boundary conditions can hardly affect final results in CFD analysis.
