Governing Equations: Please refer to the PERFORM solver documentation for details

• Numerical setup:

  • Either single (N_s = 1) or two species (N_s = 2) and no reaction

  • Molecular weight: MW = 21.32 g/mol

  • Properties of species - Calorically Perfect Gas (details here)

    • For single species, properties of reactant is used

    • For two species, both properties of reactant and product are used

• Initial conditions:

  • Single Species

    • x < 0.001 m: (T_L, u_L, p_L) = (300 K, u_IC, 1.0 MPa)

    • x >= 0.001 m: (T_R, u_R, p_R) = (2494 K, u_IC, 1.0 MPa)

  • Two Species

    • x < 0.001 m: (T_L, u_L, p_L, Y_L) = (300 K, u_IC, 1.0 MPa, 1.0)

    • x >= 0.001 m: (T_R, u_R, p_R, Y_R) = (2494 K, u_IC, 1.0 MPa, 0.0)

  • u_IC can be a user-specified constant or a specified distribution to generate 1D synthetic turbulence (details in the code setup)

• Boundary conditions:

  • Non-Reflecting Upstream and Downstream

  • Suggested downstream perturbation:

    • Forcing frequencies: 100, 200, 300, 400 and 500 kHz

    • Forcing amplitudes: 5, 10, 15, 20%
