Multiscale probability distribution of pressure fluctuations in fluidized beds

Analysis of flow in fluidized beds, a common chemical reactor, is of much current interest due to its fundamental as well as industrial importance. Experimental data for the successive increments of the pressure fluctuations time series in a fluidized bed are analyzed by computing a multiscale probability density function (PDF) of the increments. The results demonstrate the evolution of the sha...

Pressure fluctuations as a diagnostic tool for fluidized beds

The goal of this research is to determine how spectral analysis of pressure fluctuations can be used as a diagnostic and design tool for both bubbling fluidized beds (BFB) and circulating fluidized beds (CFB). Static pressure fluctuations are measured from two BFB models, two CFB models, and two Pyropower CFB boilers located at the ISU power plant/cogeneration facility. Analyzing the fluctuatio...

Granular Pressure Measurement in Fluidized Beds

Experiments were carried out to measure the additional pressure, called the granular pressure, which is exerted on the containing wail of a fluidized bed due to particle collisions with that wall. Measurements were made for water fluidized beds using glass beads of 1.3 mm and 3 mm diameter, lead shot of 2.1 mm diameter and plastic particles. The granular pressure was observed to increase to a m...

Pressure Drop in Liquid-Solid Circulating Fluidized Beds

An experiment was conducted to obtain data of pressure drop in riser tubes of liquid-solid circulating fluidized beds. In the experiment, 2 kinds of riser tube having a diameter of 24mm and 36mm were used. Tested particles were of glass and ceramics, and their diameter range was from 2.10 to 4.95mm. Water at ambient conditions was used as the fluidizing fluid. Pressure drop in riser tubes was m...

Flow through Packed Beds and Fluidized Beds

Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...
