Modeling Of Rotary Packed Beds For Reactive And Non-Reactive Systems, Chinyere Evangeline Ezeobinwune
Modeling Of Rotary Packed Beds For Reactive And Non-Reactive Systems, Chinyere Evangeline Ezeobinwune
Graduate Theses, Dissertations, and Problem Reports
Rotary packed beds (RPBs) are used in a wide range of reactive and non-reactive applications. In this research, a 2-d, first-principles, dynamic model of a non-reactive RPB that is used for heat exchange between the outgoing flue gas from a power plant and the incoming air to the boiler/pulverizer of the power plant is developed. A 2-d, first-principles model of a reactive RPB is developed where a functionalized metal-organic framework (MOF) is used for CO2 capture.
For the non-reactive system, a Ljungstrom-type air preheater (APH) is considered. Existing models for these rotating heat exchangers are typically 1-d. There are …
Literature Review On Modeling Of Density Difference Pumping Strategy For Geothermal Applications, Lucas A. Ware
Literature Review On Modeling Of Density Difference Pumping Strategy For Geothermal Applications, Lucas A. Ware
Graduate Theses, Dissertations, and Problem Reports
The utilization of geothermal ground heat sources has been demonstrated at both large and small scales across the world. However, methods of extraction of the hot working fluids are often a source of energy inefficiency and high capital expense. Current techniques to extract geothermal fluids rely on mechanically and electrically driven down-hole components that require maintenance on a regular basis. In providing a solution, one approach that reduces complexity, decreases maintenance, and allows access to fluids at greater depth is an airlift approach. The airlift approach relies on injection of gas at a depth within a geothermal well to lift …
Modeling And Tuning Of Cvt Systems For Sae® Baja Vehicles, Sean Sebastian Skinner
Modeling And Tuning Of Cvt Systems For Sae® Baja Vehicles, Sean Sebastian Skinner
Graduate Theses, Dissertations, and Problem Reports
Continuously variable transmission (CVT) describes a family of transmission styles. These systems serve the same purpose as their traditional counterparts; transmitting power while offering a variable gearing ratio. The difference lies in the CVT’s ability to change ratio continuously between a minimum and maximum without halting power transfer. They offer many benefits of an automatic transmission while being significantly lighter. For this reason, CVTs are often used on Baja SAE® vehicles to control gearing ratio.
WVU’s Baja team has used mechanical CVTs for many decades. These systems are simpler in the sense that they don’t require power to operate. …
