The velocity fluctuations of particles in a low-Reynolds-number fluidized bed have important similarities and differences with the velocity fluctuations in a low-Reynoldsnumber sedimenting suspension. We show that, like sedimentation, the velocity fluctuations in a fluidized bed are described well by the balance between density fluctuations due to Poisson statistics and Stokes drag. However, un...
The quest for novel technologies in the area of food processing & preservation has led to the application of fluidization technique for enhancing the process capabilities, energy efficiencies and overall quality retention in the final products. However, this paper reviews the various fruits and vegetables dried in the fluidized bed dryer and their retention of sensory attributes in the dried pr...
Fluidized bed gasification has proven to be an appropriate technique for converting various biomass feedstocks into helpful energy. Air distributor plate design is one of the critical factors affecting thermochemical conversion performance fluidized gasifiers. The present study proposed investigate mixing pattern and pressure drop across different configurations air distributors using a two-flu...
In this research, the generation process of engineered microsphere agarose adsorbent has been explained that has surfaces with different active sites to adsorb protein nanoparticles into the fluidized-bed system. Also, excellent selectivity of protein nanoparticles, high adsorption capacity, and fast equilibrium rate through the eco-friendly polymeric adsorbents were vital aims in here. Hence, ...
Packed bed reactor finds wide application in wastewater treatments. Packed bed reactors can be employed for aerobic and anaerobic biological treatment of wastewater. They can also be used for physico-chemical treatments such as activated carbon adsorption of various pollutants from wastewater. Packed beds with up flow and down flow mechanisms are widely used for wastewater treatment. Use of flu...
release volatile organic compounds (vocs) as environmental and occupational pollutant cause macro perspective affect such as climate change, humans and economic consequences. although fixed bed absorber is widely used as a controlling method because of its economically and availability, but these absorbers are facing some issue like high pressure drop, non-uniform distribution of flu...
