WebThe Burgers equation 3.3 is nonlinear and one expects to find p henomena sim-ilar to turbulence. However, as it has been shown by Hopf [8] and Cole [3], the homogeneous Burgers equation lacks the most important property attributed to tur-bulence: The solutions do not exhibit chaotic features like sensitivity with respect to initial conditions.

WebThe Burgers equation is a simple equation to understand the main properties of the Navier-Stokes equations. In this one-dimensional equation the pressure is neglected but the effects of the nonlinear and viscous terms remain, hence as in the Navier-Stokes equations a Reynolds number can be defined. This number expresses the ratio between … WebBurgers' equation is a well-known example of a nonlinear partial differential equation whose solution can be constructed from a linear partial differen- tial equation. It is, to the best of our knowledge, the only such example.
