| An experimental investigation was performed on a rectangular open cavity with upstream injection model in a Mach number of 1.9 using a trisonic indraft wind tunnel. |
| The development of indraft wind tunnels, however, has not been as well documented. |
| This great indraft of moist air from the equatorial North Atlantic is like the warm-season half of a monsoon. |
| And yet, at other times, there is a mysterious indraft, which irresistibly draws a passing vessel among the isles, though not bound to them. |
| Mr. Gilbert Penney: I don't know how familiar you are with the Smith Sound area, but it's a very long indraft and it's approximately half a mile wide. |
