##### 2568 Hydraulic Analysis on Microhabitat of Benthic Macroinvertebrates at Riparian Riffles

**Authors:**
Jin-Hong Kim

**Abstract:**

*Ecdyonurus kibunensis*,

*Paraleptophlebia cocorata*,

*Chironomidae*sp. and

*Psilotreta kisoensis iwata*were chosen. They showed hydraulically different habitat types by flow velocity and particle diameters of streambed materials. Habitat conditions of the swimmers were determined mainly by the flow velocity rather than by flow depth or by riverbed materials. Burrowers prefer sand and silt, and inhabited at the riverbed. Sprawlers prefer cobble or boulder and inhabited for velocity of 0.05-0.15 m/s. Clingers prefer pebble or cobble and inhabited for velocity of 0.06-0.15 m/s. They were found to be determined mainly by the flow velocity.

##### 2566 Correlation to Predict the Effect of Particle Type on Axial Voidage Profile in Circulating Fluidized Beds

**Authors:**
M. S. Khurram,
S. A. Memon,
S. Khan

**Abstract:**

^{3}, and bulk density range 890-1773 kg/m

^{3}were investigated in a gas-solid circulating fluidized bed of 0.1 m-i.d. and 2.56 m-height of plexi-glass. Effects of variables (gas velocity, particle properties, and static bed height) were analyzed on bed voidage. The axial voidage profile showed a typical trend along the riser: a dense bed at the lower part followed by a transition in the splash zone and a lean phase in the freeboard. Bed expansion and dense bed voidage increased with an increase of gas velocity as usual. From experimental results, a generalized model relationship based on inverse fluidization number for dense bed voidage from bubbling to fast fluidization regimes was presented.
