Programming the Navier-Stokes computer: an abstract machine model and a visual editor. [David Middleton; Tom Crockett; Sherryl J Tomboulian; Langley Research Center.]. The module is called "12 steps to Navier-Stokes equations" (yes, it's a tongue-in-check allusion of the recovery programs for behavioral problems).

It was inspired by the ideas of Dr. Rio Yokota, who was a post-doc in Barba's lab, and has been refined by Prof. Barba and her students over several semesters teaching the course.

In physics, the Navier–Stokes equations (/ n æ v ˈ j eɪ s t oʊ k s /), named after French engineer and physicist Claude-Louis Navier and Anglo-Irish physicist and mathematician George Gabriel Stokes, describe the motion of viscous fluid substances.

These balance equations arise from applying Isaac Newton's second law to fluid motion, together with the assumption that the stress in the. Further topics are grid generation methods and extensive discussions of the Euler and the Navier-Stokes equations.

This book offers a concise and gentle introduction to finite element programming in Python based on the popular FEniCS software library. Using a series of examples, including the Poisson equation, the equations of linear elasticity, the incompressible Navier–Stokes equations, and systems of nonlinear advection–diffusion–reaction equations, it guides readers through the essential steps to /5(9).

For an incompressible fluid $\dot\rho=0$. Then the continuity equation implies $$ \nabla\cdot u = 0. $$ We can now take the divergence of the Navier-Stokes equation and get $$ -\nabla^2 P = \rho\nabla_j(u_i\nabla_i u_j). $$ This means that the pressure is instantaneously determined by the velocity field (the pressure is no longer an independent hydrodynamic variable).

The general approach of the code is described in Section in the book Computational Science and Engineering [4].
