This paper by Sam Clark of CPFD Software illustrates a multiphase simulation of a commercial-scale fluidized catalytic cracking unit with complex internal geometries and how the computational model can be used to predict wear on internal structures.
Standpipes are often the bottleneck in a circulating fluidized bed processes. Understanding the pressure build and dissipation in a standpipe is critical in designing and operating a standpipe that can meet production needs.
The main objective of this study is to shed light on the mechanism by which this erosion takes place, and how different design and operating parameters affect the erosion.
This work shows the development of a three-optical fiber probe to study the behavior of the bubble in bubbling fluidized gas-solid beds.
In this work, James Parker presents a CPFD model compared with JPL data for the deposition rate, silicon fines production, and temperature distribution within a silane deposition reactor.
In this CPFD Software whitepaper by James Parker, a reactor using solid MGS particles fluidized by hydrogen chloride gas which reacts to form primarily TCS and hydrogen gas is discussed.
Snider, Clark and O’Rourke present an extension of the CPFD methodology to include an enthalpy equation that describes energy transport for fluid, and provides for transfer of sensible and chemical energy between phases and within the fluid mixture, with application to a fluidized bed coal gasifier.
