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...
1. A muffling device, comprising: an inner flow conditioner shaped as a generally conical frustum comprising an upstream base and a downstream base, a diameter of the upstream base being larger than a diameter of the downstream base, the inner flow conditioner comprising an inlet approximate the upstream base,a generally circular inner flow conditioner downstream end wall having an inner flow conditioner downstream end wall area, the inner flow conditioner downstream end wall being generally orthogonal to a longitudinal axis of the conical frustum and co...
