Design, Fabrication, And Testing Of A Miniature Impulse Turbine Driven By Compressed Gas, Daniel B. Holt
Design, Fabrication, And Testing Of A Miniature Impulse Turbine Driven By Compressed Gas, Daniel B. Holt
Theses
A miniature impulse turbine has been developed at the Rochester Institute of Technology. The goal of this project was to design, fabricate, and test a miniature turbine intended to power small vehicles such as micro air vehicles (MAVs). MAVs are vehicles with a maximum dimension of less then 15 cm and are used for surveillance and scouting. Due to the small size of MAVs, weight is a key design parameter. The batteries alone can account for more than 50% of the weight of the entire vehicle. A miniature turbine driven by compressed gas and coupled to a generator has been …

Cfd Analysis And Validation For Solution To Micro Air Vehicle Airframes, Taher I. Attari
Theses
Micro Air Vehicles (MAVs) are generally defined as having an airframe with a span less than 6 inches and a mass less than 100 grams. The design of airframes is currently hindered by the lack of thorough understanding of the flow physics of very small aircrafts flying at low speeds. The study investigates the use of Fluent, a licensed CFD code at RTT, for MAV airframe design. This study is carried out in 4 steps. First, 4 different airfoils are selected and tested in CFD. The next step included the simulation of 3-D flat plates and wing models. An external …

Simulating Particle Deposition In A Human Replica Lung Model, Pravir Rai
Theses
Tobacco consumption causes a variety of respiratory diseases including lung cancer and chronic obstructive pulmonary disease. These diseases occur when pathogens present in cigarette smoke enter into the respiratory system and deposit in the airways or gas exchanging membranes. Computational Fluid Dynamics (CFD) package FLUENT has been applied to study the deposition patterns of cigarette smoke particles from sidestream and mainstream smoke, as well as carcinogen size specific particles for NNK and BaP. A three dimensional cast of an ideal three generation Weibel lung model and a three dimensional morphologically accurate human replica lung model were used in the analysis. …
