Quantify pressure-induced forces on walls, in particular with static fluids
Concept of pressure; Pressure in static fluids; Wall pressure forces and buoyancy.
Understand the concept of shear, and quantify shear-induced wall forces for simple cases
Concept of shear; Slip and viscosity; Wall shear forces.
Analyze existing flows, and quantify the forces and moments associated with them
The Reynolds Transport Theorem; Mass conservation; Change of linear momentum; Change of angular momentum; Energy conservation; the Bernoulli equation; Limits of integral analysis.
Predict fluid flow in the most general terms possible, and understand the nature of CFD
Eulerian description of fluid flow; Mass conservation; Change of linear momentum; Change of angular momentum; Energy conservation; CFD: the Navier-Stokes equations in practice.
Understand duct flow, and quantify pressure losses in pipe installations
Inviscid flow in ducts; Viscous laminar flow in ducts; Viscous laminar flow in cylindrical pipes; Viscous turbulent flow in cylindrical pipes.
Scale flows and measurements up and down to facilitate observation
