1.) Flow through nozzle: This exercise was jointly developed with Professor Thomas Barber of the Mechanical Engineering Department at the University of Connecticut. In this exercise, two-dimensional or axisymmetric flow through a converging-diverging nozzle is modeled. The nozzle can be defined as a two-dimensional or axisymmertric geometry. Coarse, medium, and fine mesh types are available. Both inviscid and viscous flow conditions can be considered. The material properties of air are used with ideal gas behavior assumed for the density calculations. Inlet Mach number, exit pressure, pressure ratio, and inlet temperature can be specified. Average Mach number at the outlet is reported. Contours of pressure, velocity, temperature, Mach number, stream function, turbulent kinetic energy, and dissipation rate can be displayed. A velocity vector plot is also available.
