GOALS: 1) To understand concepts of kinetic theory and
its application to rarefied flows. 2) To
understand and be able to solve problems with real gases in one- dimensional
flow, including real gas flows, combustion waves and non-steady flows
and unsteady test devices.
OBJECTIVES: 1) Understand pressure, temperature, internal storage, mean free path
and transport properties from a molecular
point-of-view.
2) Be able to calculate aerodynamics of bodies in free-molecular
flow.
3) Be able to apply the law of mass action.
4) Be able to calculate and contrast 1-D ideal and real gas flows.
5) Understand non-steady waves and be able to predict performance of
test devices that operate with non-steady
1D gas dynamics.
6) Be able to calculate combustion waves.
TOPICS: 1) Kinetic theory: model, wall
collisions, temperature and equation
of
state, mean free path, transport properties. (5
hours)
2) Free molecule flow: model, surface collisions, forces and heat
transfer. (3
hours)
3) Thermodynamics: law of mass action, applications, thermo-
dynamics
of air. (4
hours)
4) One-dimensional flow: review steady 1-D flow,
real gas flows,
re-entry
flow (5
hours)
5) One-dimensional wave motion: propagating
waves, Riemann
Invariants,
applications, explosion waves. (3
hours)
6) Additional applications: nozzles and
diffusers, hypersonic flow. (5
hours)
