The Compressible Flow Project | |
In addition to the assignments listed above, there is a quite extensive project course element in the course that spans over all eight course weeks. The outline of the project is given in short below.
|
|
Case 1 (project groups 1 & 8) Inviscid flow through engine intake: The flow field inside a supersonic engine intake (SR-71 Blackbird) will be calculated both analytically and numerically. The flow is assumed to be steady and two-dimensional. |
|
Case 2 (project groups 2 & 9) Unsteady and steady inviscid compressible flow around airfoil: The unsteady flow developing around an airfoil after an impulsive start will be simulated numerically. The solution should (after some time) converge towards a steady-state flow condition. The flow is assumed to be two-dimensional. In addition, a supercritical airfoil is investigated and results are compared. |
|
Case 3 (project groups 3 & 10) Inviscid compressible under-expanded nozzle flow: The steady state flow in and outside of a convergent nozzle including possible shocks downstream of the nozzle will be calculated numerically. The flow is assumed to be steady, two-dimensional, and axisymmetric. |
|
Case 4 (project groups 4 & 11) Inviscid compressible over-expanded nozzle flow: The steady state flow in and outside of a convergent-divergent nozzle including possible shocks inside and downstream of the nozzle will be calculated numerically. The flow is assumed to be steady, two-dimensional, and axisymmetric. |
|
Case 5 (project groups 5 & 12) Supersonic flow over a bi-convex airfoil: The supersonic flow over a bi-convex airfoil is investigated both numerically and analytically. The numerical predictions are compared with the analytical solution and available experimental data. |
|
Case 6 (project groups 6 & 13) Inviscid supersonic flow over a 2D compression/expansion ramp: The supersonic flow over a compression/expansion ramp is investigated both numerically and analytically. The numerical predictions are compared with the analytical solution. The detached shock limit is investigated. |
|
Case 7 (project groups 7 & 14) Supersonic flow over a gradual 2D compression ramp: The supersonic flow over a gradual compression ramp is analysed numerically. Both inviscid and viscous simulations are done and results are compared. |
