YOU MUST SUBMIT YOUR APPLICATION VIA GRANTS.GOV TO BE CONSIDERED FOR AN AWARD. Advanced diagnostics are needed for probing the fluid dynamics of solids and gas solids flow systems. Detailed information on solids and gas-solids flow structure is needed for validation of computational fluid dynamic (CFD) models. Diagnostics of interest include, but are not limited to, imaging of solids concentration, wall shear, local gas and solids velocities and concentrations (with up to 20% solids), gas and solids dispersion, turbulence, and granular temperature. These topics of interest are discussed in more below. Gas-Solids Distribtion: Advanced 3-dimensional imaging of gas-solids distribution is sought to measure voidages > 80% over a short time scales to help identify particle clusters. In order to avoid wall effects these measurements are desired in a circulating fluidized bed riser or transport reactor of 12 or larger in diameter with the ability to vary the axial location from the entrance, fully developed regions, and near the outlet of the riser. Wall Shear Measurement: Shear at the wall of a circulating fluid bed riser is a critical boundary condition used by CFD codes for which sufficient information is not currently available. New, accurate approaches are sought to make these measurements on a local basis using Micro Electrical Mechanical Systems (MEMS) or optical interferometry with hair-like fibers, or similar technologies. Data Analysis: Mathematical analysis methods are required to identify necessary and sufficient criteria for model validation using experimental results. Criteria and identification are required for local, micro-scale, gas-solids flow structures in circulating and transport fluid beds such as particle cluster size, concentration in order to compare and validate CFD simulations with experimental data. For example, further development is required for various de-convolution techniques such as wavelet analysis to separate cluster characteristics from diagnostic data from high speed pressure fluctuations, optical data, and gas tracer measurements. Solids Circulation Rate: A method is needed to continuously monitor the circulation rate in the moving bed region of standpipes in hot circulating fluid bed reactors. Advanced power generation concepts such as chemical looping processes require the careful control of solids flow between three or more different fluid bed reactors operating at elevated temperatures. Currently there is no means to measure these solids flows.
