The material of chapter 7 is adapted from the textbook nonlinear dynamics and chaos by steven.
As explained on pages 2325 of inces book, the nonlinear riccati equation can always be reduced to a second order linear ordinary differential. Enough in the box to type in your equation, denoting an apostrophe derivative of the function and press solve the equation. It puts into a relation pressure and velocity in an inviscid incompressible flow. It is one of the most importantuseful equations in fluid mechanics. F ma v in general, most real flows are 3d, unsteady x, y, z, t. The sum of the pressures and mechanical energy per unit volume, is constant along the flow tube. This online calculator allows you to solve differential equations online. Show that the transformation to a new dependent variable z y1.
