Superconducting Bearing Design for Outer Rotor Flywheel Using Lumped Parameter Techniques

This paper describes the application of lumped parameter modeling techniques to designing high temperature superconducting bearings for outer-rotor flywheel energy storage systems. The lumped parameter models decrease computational time by 99% compared to Finite Element Analysis (FEM) without compromising fidelity needed to capture the non-linear and hysteretic force-displacement behavior between a levitated permanent magnet and bulk superconductor. The techniques formulated can be used to quickly evaluate lifting capacity and translational stiffness for a superconducting bearing design. The validity of the modeling approach has been verified by comparing results from FEM studies and experimental tests.Center for Electromechanic

Prime mover and energy storage considerations for a hydrogen-powered series hybrid shuttle

This paper describes simulation results obtained through modeling the operation of a 6.7 m long hydrogen-powered shuttle bus. The actual shuttle bus and its hydrogen refueling station constitute the first of its kind in the state of Texas. The simulations are used to initially verify the stated performance of the shuttle bus and to validate the modeling approach. The vehicle model is then modified to assess the predicted changes in performance, efficiency, and route following capability while conducting a parametric study involving fuel cell and internal combustion prime movers as well as chemical battery and flywheel energy storage systems. Simulation results show that a fuel cell-powered shuttle bus with a high power density, low mass energy storage system provides the highest vehicle range and lowest energy consumption.Center for Electromechanic

Prebiotics, Probiotics, Synbiotics and Functional Foods in Control and Treatment of Type II Diabetes Mellitus and Colorectal Cancer

Prebiotics, probiotics and synbiotics are components that enhance human health by several mechanisms. Patients suffering from type II diabetes mellitus (T2DM) and colorectal cancer have seen benefits when treated with a prebiotic, probiotic or synbiotic therapy. These benefits include the improvement of their lipid profile, oxidative stress status, as well as the modulation of the inflammatory and immune responses. The associated benefits of prebiotic, probiotic or synbiotic functional foods have been studied, showing promising results into the prevention or control of diabetes and colorectal cancer. This novelty research provides new evidence that the use of functional foods along with medical therapy could be used to further enhance patient’s health

Reduced-Order Dynamic Model of Permanent Magnet and HTSC Interaction in an Axisymmetric Frame

This paper presents a reduced order model for a permanent magnet (PM) and high-temperature superconductor (HTSC) in an axisymmetric frame. This model is formulated as a bond-graph to aid integration into system models for applications such as lift bearings, where the nonlinear force–displacement interactions are important for stability analysis and control design. The reduced-order model is based on the mechanical and electromagnetic interaction between a PM and bulk HTSC. Performance of the proposed reduced-order model is compared to finite element method (FEM) analysis and experimental tests to confirm the static and transient performance.Center for Electromechanic
