11. This trade-off is sometimes represented in what is called an Euler equation . 12. In 1726, Euler equations which could be applied to both compressible and incompressible flows. 13. In this context, this equation is also one of the Euler equations ( fluid dynamics ). 14. Traditionally the Newton Euler equations is the grouping together of moments ) acting on the rigid body. 15. Usually the equations of motions are derived from the Newton-Euler equations or Lagrange s equations. 16. Since air and water are governed by similar Euler equations , exerts an upward force on the foil. 17. The Newton Euler equations combine the forces and torques acting on a rigid body into a single equation. 18. Euler equations in the Froude limit ( no external field ) are named free equations and are conservative.19. One splits the Euler equations or the Navier-Stokes equations into an average and a fluctuating part. 20. High resolution simulation of Euler equations based on G A Sod's'Shock Tube'problem.
