batch adsorber design for different solution volume adsorbent mass ratios using the experimental equilibrium data with fixed solution volume adsorbent mass ratio of malachite green onto orange peel
Dyes and Pigments, 2007Co-Authors: Vasanth K Kumar, K PorkodiAbstract:Abstract Equilibrium studies were carried out at 305 K for the sorption of malachite green onto orange peel for a fixed Operating Line condition (solution volume/adsorbent mass ratio or V / M ratio). The experimental data were fitted to the Freundlich, Langmuir and Redlich–Peterson isotherms by non-Linear method. The best fitting isotherm was found to be the Langmuir and Redlich–Peterson isotherm. Redlich–Peterson is a special case of Langmuir isotherm when the constant g equals unity. A single stage batch adsorber was designed for different Operating Line ( V / M ) ratios using the Redlich–Peterson isotherm. Equilibrium data were obtained from the Langmuir isotherm at different V / M ratios using the mass balance equation for the batch adsorber system. A simple Linear expression relating the parameters involved in the batch adsorber design was proposed for the studied system.

Experimental investigation of the effect of rotor tip gaps on 3D separating flows inside the stator of a highly loaded compressor stage
Experimental Thermal and Fluid Science, 2016Co-Authors: Baojie Liu, Zhibo ZhangAbstract:Abstract Flow separations in compressor blade passages are common and can cause significant flow blockage and loss production. This paper investigates experimentally the three-dimensional (3D) flow separations in a highly loaded low-speed large-scale compressor facility. Oil flow visualizations, stereoscopic particle image velocimetry (SPIV), and five-hole probe measurements are conducted at certain conditions from the near-chock to near-stall condition along the compressor Operating Line. The 3D separation and vortex flow structures in the stator at different Operating conditions are analyzed. By changing the size of the rotor tip gap, six groups of oil-flow pictures are obtained to study the effect of the rotor gaps on the 3D separating flows in the downstream stator. The variation of the corner separation scale is almost Linear with the rotor tip gap size. Along the compressor Operating Line, four typical 3D flow structures are found inside the stator passage. Between the second typical 3D flow structure and the third typical 3D flow structure, an unstable stage exists on the compressor Operating Line; during this stage, the hub corner separation becomes an open separation from the closed type. A smaller rotor tip gap corresponds to an earlier unstable stage. Finally, a critical rotor tip blockage state usually existed for the transform of corner separation types at a certain rotor tip gap configuration. This discovery is valuable for the study of multistage compressor matching problems at off-design conditions.
