There are many situations in which a computational approach is the ideal one for studying a problem. For example, in studying the flow of air in the breathing tract of a human, one can hardly do experiments! And even if we could experiment, how could we *see* what is happening? By simulation, we can…

Lecture "zero" (2012) part 2: Derivation of the Equation of Conservation of Momentum

Play Episode Listen Later Jan 16, 2012

Part 2 of a 3-part review of the derivation of the differential form of the fluid equations, this "pencast" explains the derivation of the equation of conservation of momentum by making a balance of forces of a small (infinitesimal) volume of fluid. Assuming no shearing stresses, it concludes with the Euler equations in vector form.
