Flooding can lead to significant damage and loss of life. Flood planning is critical to mitigating losses in the event of disasters. In most civil engineering programs that teach about flood planning, it is not economically viable to develop a physical laboratory setup to simulate flood scenarios. A simulated flood based on a 2008 flood in Northwest Indiana was modeled to provide a virtual laboratory using HEC-HMS and HEC-RAS models but only in the form of numbers or graphs. A three dimensional (3D) virtual lab module was needed to engage civil engineering students to explore flooding case studies, visualize hydraulic simulation results, and improve learning about flood planning.
The city of Hamilton, OH Municipal Electric Plant (Hamilton), operates a pulverized coal fired boiler (No. 8) subject to the boiler Maximum Achievable Control Technology (MACT) standards issued by the US EPA. EQ Engineers, LLC (EQE) has been employed by Hamilton to study and evaluate options for achieving MACT standards on a consistent basis as part of an overall compliance plan. The current configuration of the ductwork leading into the Electrostatic Precipitator (ESP) is not producing a uniform flow pattern. It is believed that the variation in flow velocity across the face is contributing to particulate matter (PM) emissions that exceed the MACT standards.
The issue of transferring learned concepts to practical applications is a widespread problem in postsecondary education. Related to this issue is a critical demand to educate and train a generation of professionals for the wind energy industry. With initiatives such as the U.S. Department of Energy’s “20% Wind Energy by 2030” outlining an exponential increase of wind energy capacity over the coming years, revolutionary educational reform is needed to meet the demand for education in the field of wind energy.
A venturi scrubber is a device which utilizes liquid to remove fine particulates from gaseous streams. ArcelorMittal USA has developed a pollution control process using venturi scrubber for removal of particulates from the exhaust gas in a sinter plant. However, excessive wear on the side wall of the throat has been found leading to considerable production downtime. Achieving a reduction in wear and effective optimization of the scrubber’s performance with increased efficiency requires a better understanding of the flow inside the device. In this condition, a new methodology is required to simulate the venturi scrubber operation in order to optimize the design.
