Workshop’s objectives

• To assess non-deterministic methodologies on compulsory test cases
• To promote and stimulate the development and application of the non-deterministic methodologies
• To review the state of the art by renowned keynote speakers
• To present the developments and results of the NODESIM- CFD consortium

Academics and professionals from aeronautical community are encouraged to participate in this workshop with contributions directed to one of the workshop’s objectives. in addition to paper contributions, participants are expected to contribute nondeterministic simulation results, concerning at least one of the two compulsory test cases selected by the organizers.

TEST CASE 1

The first test case is the transonic flow around the RAE 2822 airfoil at Mach number M=0.734; angle of incidence 2.79 deg and Reynolds number Re= 6.5x10^6.
Uncertainties are imposed on the angle of incidence, the thickness-to-chord ratio and the Mach number.

Contributors are expected to deal both with the case where these uncertainties have a uniform distribution and the case where they have a normal distribution.

The required outputs are the probability density functions, mean and standard deviations for: drag; lift and moment coefficients. Analysis should be based on a RANS solver.

TEST CASE 2

The second test case is the flow in the transonic axial compressor, known as NASA Rotor 37.
Uncertainties are imposed on the inlet total pressure, the static outlet pressure and the tip clearance.

	Uncertain parameter	The most likely value (m)	Minimum value (a)	Maximum value (b)	PDF type
1	Inlet total pressure	Experimental input profiles (m)	95% m	105% m	Beta pdf
2	Static outlet pressure	mp=1.1 bar	98% mp	102%mp	Beta pdf
3	Tip clearance	mH=0.356 mm	50% mH	150%mH	Beta pdf

The computed results will be represented as bar plots on profiles of the pressure ratio, isentropic efficiency and total temperature ratio versus mass flow.
