The TidGen Power System generates emission-free electricity from tidal currents and connects directly into existing grids using smart grid technology. The power system consists of three major subsystems: shore-side power electronics, mooring system, and turbine generator unit (TGU) device. This submission includes the preliminary turbine hydrodynamic design, with supporting CFD analysis, structural analysis, and design description for TidGen versions 1.0 and 2.0.

MFiX (Multiphase Flow with Interphase Exchanges) is an open source, general-purpose computer code developed at NETL for describing the hydrodynamics, heat transfer and chemical reactions in fluid-solids systems. MFiX calculations give transient data on the three-dimensional distribution of pressure, velocity, temperature, and species mass fractions. Users can download the code, documentation, and see examples of code application.
The hydrodynamics and the mixing properties in a 15.2 cm diameter x 335.3 cm high stainless steel column with three phases (air, water and coal) in cocurrent upflow were studied. The effect of solids particles size, solids concentration, slurry velocity and gas velocity on gas holdup and heat dispersion coefficients were determined. All the experimental data were correlated empirically and the results were compared with other published literature. Theoretical explanations of some results were provided
