Sketch of a porous tube with variable headwall injection.
Streamlines for depicted in the plane for the uniform headwall injection case. Results shown in (a)–(f) are enhancements that illustrate the streamline curvature in different sectors of the chamber.
Same as above except for .
Radial evolution of the streamwise velocity corresponding to . This value may be associated with a simulated SRM with reactive headwall. Results are shown at (a) and (b) six equidistant positions corresponding to , 0.4, 0.8, 1.2, 1.6, and 2.
Radial evolution of the streamwise velocity for and several headwall inlet profiles associated with (a)–(b) Berman’s half-cosine, (c)–(d) Poiseuille, , (e)–(f) , and (g)–(h) . As in Fig. 4, results are shown at the headwall (left) and six equidistant positions corresponding to , 0.4, 0.8, 1.2, 1.6, and 2 (right).
Comparison between inviscid analytical and numerical simulations for (a) uniform, (b) half-cosine, and (c) Poiseuille injection profiles in a cylindrical chamber using and , respectively. Hollow circles denote computational results. Axial positions correspond to .
Same as above except for the axial velocities being enlarged for better comparison.
