Weekley, Scott (2021-05)This body of work details the design and analysis, as well as discussion of requirements for eventual fabrication and flight testing, of a flying-wing aircraft. The design presented is focused primarily on matching the ... -
Design and Development of a Severe Storm Research UAS
Avery, Alyssa Shearon (2015-05-01)A small unmanned aircraft system (SUAS) was designed and developed to be utilized for meteorological data collection, specifically information useful for severe storm and tornado prediction. The system will operate prior ... -
Design and development of a water observatory: An autonomous environmental sampling system for in-situ sensing of lakes and rivers
Jdiobe, Muwanika (2020-12)This project focuses on the design, development, and implementation of an autonomous system, or unmanned surface vessel (USV), known as MANUEL (Mobile Autonomously Navigable USV for Evaluation of Lakes). MANUEL is an ... -
Design and Installation of a High Reynolds Number Recirculating Water Tunnel
Daniel, Libin (Oklahoma State University, 2014-07-01)The High-Reynolds Number Fluid Mechanics Laboratory has recently been established at Oklahoma State University (OSU). The three primary components of the laboratory are 1) a recirculating water tunnel, 2) a multiphase pipe ... -
Design of a Rocket Launched Sounding Uas
Fehrenbach, Shea Donald (2016-07-01)Current diagnostic tools used to sample the thermodynamic structure of the AtmosphericBoundary Layer (ABL) include radiosondes, manned aircraft, radar, andtowers. One objective, for sampling the atmosphere, is to supplement ... -
Development and evaluation of a 360° differential pressure gust sensor for extreme weather environments
Cole, Andrew (2022-07)Measuring rapidly fluctuating high wind speeds and direction in the extreme weather environments of severe storms proves to be a difficult task with current sensors. For example, mechanical anemometers do not provide ... -
Development of a Low Cost Unmanned Aircraft System for Atmospheric Carbon Dioxide Leak Detection
Mitchell, Taylor Austin (2015-05-01)Carbon sequestration, the storage of carbon dioxide gas underground, has the potential to reduce global warming by removing a greenhouse gas from the atmosphere. These storage sites, however, must first be monitored to ... -
Development of a micro air vehicle for meteorological soundings
Walsh, Andrew (2021-12)To have accurate forecasting models for weather systems, data must be collected on the thermodynamic structure of the Atmospheric Boundary Layer (ABL). Currently this information is gathered using weather balloons, but ... -
Effect of a Symmetric Contraction on the Concentration Profiles of a Particleladen Slurry
Deshpande, Abhishek (Oklahoma State University, 2010-12-01)The effect of a symmetric contraction on the concentration profiles of a xylene- 2 amino, 4, 6 dimethyl pyrimidine (ADP) slurry flowing in a cylindrical pipe were simulated using computational fluid dynamics. ANSYS FLUENT ... -
