NIPSCO Unit 7 Selective Catalytic Reduction Flow Model Analysis

Unit 7 at the NISPSO Bailly Generating Station is equipped with selective catalytic reduction (SCR) systems to comply with environmental regulations for NOx control. However, Unit 7 SCR experienced problems with ash build-up on its catalyst layers (Figure 1) and turning vanes. The pluggage map showed that the ash accumulation was extremely serious on the first catalyst layer. The build-up led to higher differential pressures across the layers as well as increased maintenance costs for ash removal.

3D Simulation and Visualization of Horizontal Axis Wind Turbines

Wind turbines are a growing source of renewable energy generation. Typically, they are installed in large groups, called wind farms, and connected to the electrical distribution grid. In order to maximize the power output of these turbines, the aerodynamic forces that operate on the rotor blades must be examined. In this project, a large scale Horizontal Axis Wind Turbine (HAWT) modeled loosely after the GE 1.5 MW wind turbine is examined. Computational Fluid Dynamics (CFD) simulations are performed on the turbine in both single and wind farm arrangements to determine various aerodynamic flow characteristics of the turbine.

A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. Understanding the wind turbine organization and the energy transformation has long been challenging for many engineering students. As a new approach in teaching wind energy, an interactive computer program was developed to provide students with hands-on experience in visualizing and manipulating wind turbine.

Location and placement of wind turbines can have a significant effect on their energy output and maintenance needs. However, the siting process includes many additional variables such as the visual impact of on the local environment. Augmented Reality (AR) is a technology that allows simulation data and 3D models to be overlaid on top video of a real environment in real-time. By applying AR to the issue of wind turbine siting, students and the public alike can gain a better understanding of location on wind turbine performance and visual impacts.
