Governing Equations for Flow in GeneralCoordinates
We collect the transport equations for a multi-component, multi-temperaturenon-equilibrium flow.1 All transport equations have been discussed in Chap-ter 4, as well as in Chapters 5, 6, 7 (see also [2]–[4]). We write the equationsin (conservative) flux-vector formulation, which we have used already for theenergy equation in Sub-Section 4.3.2, and for three-dimensional Cartesiancoordinates:
∂Q
∂t+
∂(E + Evisc)
∂x+
∂(F + F visc)
∂y+
∂(G+Gvisc)
∂z= S. (A.1)
Q is the conservation vector, E, F , G are the convective (inviscid) and Evisc,Fvisc, Gvisc the viscous fluxes in x, y, and z direction. S is the source termof mass and of vibration energy.
The conservation vector Q has the form
Q = [ρi, ρu, ρv, ρw, ρet, ρmevibr,m], (A.2)
where ρi are the partial densities of the involved species i, Section 2.2, ρ isthe density, u, v, w are the Cartesian components of the velocity vector V , et= e + 1/2 V 2 is the mass-specific total energy (V = |V |), Sub-Section 4.3.2,and evibr,m the mass-specific vibration energy of the molecular species m.
The convective and the viscous fluxes in the three directions read
E =
⎡

(A.5)The convective flux vectors E, F , G represent from top to bottom the
transport of mass, Sub-Section 4.3.3, momentum, Sub-Section 4.3.1, of totalenergy, Sub-Section 4.3.2, and of non-equilibrium vibration energy, Section5.4.2 In the above ht = et + p/ρ is the total enthalpy, eq. (5.7).
In the viscous flux vectors Evisc, F visc, Gvisc, the symbols jix etc. rep-resent the Cartesian components of the diffusion mass-flux vector j
iof the
species i, Section 4.3.3, and τxx, τxy etc. the components of the viscous stresstensor τ , eqs. (7.10) to (7.15) in Section 7.1.3. In the fifth line each we havethe components of the energy-flux vector q
e, eq. (4.58), Sub-Section 4.3.2,
which we have summarized as generalized molecular heat-flux vector in eqs.(4.61) and (4.62), the latter being the equation for the heat flux in the gas atthe wall in the presence of slip flow. In the sixth line, finally, we find the termsof molecular transport of the non-equilibrium vibration energy in analogy tothe terms of eq. (4.59).
The components of the molecular heat flux vector q in the viscous fluxvectors in eqs. (A.3) to (A.4) read, due to the use of a multi-temperaturemodel with m vibration temperatures
⎛

⎠ = −ktrans∇Ttrans +∑
m
kvibr,m∇Tvibr,m. (A.6)
The source term S finally contains the mass sources Smi of the speciesi due to dissociation and recombination, eq. (4.84) in Sub-Section 4.3.3, andthe energy sources Qk,m
2 We have not given the equation(s) for the transport of vibrational energy inSection 5.4, but have referred instead to [5].

The terms Qk,m represent the k mechanisms of energy exchange of them vibration temperatures, for instance between translation and vibration,vibration and vibration, etc., Sub-Section 5.4.
To compute the flow past configurations with general geometries, theabove equations are transformed from the physical space x, y, z into thecomputation space ξ, η, ζ:
ξ = ξ(x, y, z),
η = η(x, y, z),
ζ = ζ(x, y, z).
(A.8)
This transformation, which goes back to H. Viviand [6] and to M. Vinokur[7], regards only the geometry, and not the velocity components. This isin contrast to the approach for the general boundary-layer equations, Sub-Section 7.1.3, where both are transformed. ξ usually defines the main-streamdirection, η the lateral direction, and ζ the wall-normal direction, however ingeneral not in the sense of locally monoclinic coordinates, Sub-Section 7.1.3.
The transformation results in
∂Q
∂t+
∂(E + Evisc)
∂ξ+
∂(F + F visc)
∂η+
∂(G+ Gvisc)
∂ζ= S, (A.9)
which is the same as the original formulation, eq. (A.1).The transformed conservation vector, the convective flux vectors, and the
source term are now
U = J−1U,
E = J−1[ξxE + ξyF + ξzG],
F = J−1[ηxE + ηyF + ηzG],
G = J−1[ζxE + ζyF + ζzG],
S = J−1S,
(A.10)
with J−1 being the Jacobi determinant of the transformation. The trans-formed viscous flux vectors have the same form as the transformed convectiveflux vectors.
The fluxes, eqs. (A.3) to (A.5), are transformed analogously, however wedo not give the details, and refer instead to, for instance, [8, 9].
