초록

Some example muffling devices may include an inner flow conditioner shaped as a generally conical frustrum and a generally cylindrical an exhaust can around the inner flow conditioner. A ratio of a downstream end wall area of the inner flow conditioner to a downstream end annular area between the downstream end wall and the exhaust can may be about 0.12 to about 0.97. A ratio of the downstream end annular area to the downstream end wall area may be proportional, by a factor of about 0.8 to about 1.9, to a ratio of an effective area of the inner flow cond...
