Pitot Version: 15-Aug-2018 doing an expansion tube calculation
|
|
state 4 is the driver condition.
|
|
state 1 is shock tube fill. state 5 is acceleration tube fill.
|
|
state 2 is the shocked test gas.
|
|
state 7 is expanded test gas entering the nozzle.
|
|
state 8 is test gas exiting the nozzle (using area ratio of 5.64).
|
|
state 10f is frozen shocked test gas flowing over the model.
|
|
state 10e is equilibrium shocked test gas flowing over the model.
|
|
state 10c is conditions over 15.0 degree conehead in the test section.
|
|
Solver used is perfect gas.
|
|
Test is 'fulltheory-pressure'
|
|
Facility is x2.
|
|
Driver gas is He:0.80,Ar:0.20.
|
|
Test gas (state 1) is gasgiant_h285ne (gamma = 1.6078, R = 476.310512747).
|
|
Accelerator gas (state 5) is Air.
