CFD simulations all external boundaries excluding symmetry plane
are defined as pressure far field whereas pressure outlet boundary condition is given to the engine face.
The double-sided planar LIF was implemented in the investigation, wherein via a system of lenses and mirrors a krypton fluoride (KrF) excimer laser beam (wavelength 248 nm) was reshaped and evenly split into two planar light sheets that were then coupled into the same symmetry plane
of the combustion chamber from two opposite sides through the glass liner.
z=0, x=0 and y=0 define the floor, the nozzle exit plane and the symmetry plane
The initial solution [L.sup.(0)] for the iterative numerical scheme is an ellipsoid with [a.sup.(0)] = -40.893 cm, [b.sup.(0)] = -0.077795, [c.sup.(0)] = 0, and [d.sup.(0)] = 0.62708, which provides a beamwidth equal to the specification in the symmetry plane
, [[alpha].sub.u] = 8[degrees].
The meshes in the computational domain are all tetrahedral structures generated on the platform of ICEM, and the meshes over the shell and the longitudinal symmetry plane
of car are shown in Figure 21.
For each surface, the principal plane of symmetry is identified as the symmetry plane
that aligns with, or runs parallel to, the G-or H-axis respectively; see Figures 3(d) and 4(d).

As the reachable scan volume with the 4 x 4 array is restricted to approximately [+ or -]1[degrees], the position of the multifeed array can be precisely shifted along x-axis so that in the symmetry plane
any scan angle up to [+ or -]10[degrees] can be achieved.
Half of six columns, which is split by a symmetry plane
(Figure 2), has been modeled in order to reduce computational complexity, time, and cost of simulation.
The computational domain consists of inflow plane, outflow plane, outer boundary, hull surface, and symmetry plane
as shown in Figure 5.

From the circuit viewpoint, the symmetry plane
is a virtual ground under differential-mode excitation, and the resulting circuit is a normal CRLH unit-cell.
