Simplified continuity equation

WebbSimplified or complete forms of the Navier-Stokes equations are employed in the design of trains, cars, aircraft, power stations, and blood flow. The Navier-Stokes equations are a collection of three fundamental equations: The continuity equation governs the conservation of mass in a physical problem. The momentum equation, ... WebbTo keep the details simple, we will illustrate the fundamental ideas underlying CFD by applying them to the following simple 1D equation: du dx +um = 0; 0 ≤ x ≤ 1; u(0) = 1 (1) We’ll first consider the case where m = 1 when the equation is linear. We’ll later consider the m = 2 case when the equation is nonlinear.
