On The Fuel Spray Applications Of Multi-Phase Eulerian Cfd Techniques, Gabriel Lev Jacobsohn
Masters Theses
Eulerian-Eulerian Computational Fluid Dynamics (CFD) techniques continue to show promise for characterizing the internal flow and near-field spray for various fuel injection systems. These regions are difficult to observe experimentally, and simulations of such regions are limited by computational expense or reliance on empiricism using other methods. The physics governing spray atomization are first introduced. Impinging jet sprays and Gasoline Direct Injection (GDI) are selected as applications, and modern computational/experimental approaches to their study are reviewed. Two in-house CFD solvers are described and subsequently applied in several case studies. Accurate prediction of the liquid distribution in a like-doublet impinging jet …
Cfd Study Of Aerodynamic Drag Reduction Tool Of A Generic Sports Utility Vehicle (Suv), Samira Ishrat Jahan
Cfd Study Of Aerodynamic Drag Reduction Tool Of A Generic Sports Utility Vehicle (Suv), Samira Ishrat Jahan
Masters Theses
The Sports Utility Vehicle (SUV) has been a popular automobile choice in North America for over 50 years due to its seating and hauling versatility and good towing capacity. This widespread popularity has resulted in manufacturers pushing for increased horsepower and cabin size. Unfortunately, the limiting factor has been fuel economy which is governed by the vehicle aerodynamics. A reduction in aerodynamic drag can result in better fuel economy. The goal of this study is to reduce the aerodynamic drag of a generic SUV and the efficient application of drag reduction devices to control flow separation. An initial study has …
Study Of Cooling-Drag In A Generic Passenger Car Using Cfd And Wind Tunnel, Md Maruf Hossain
Study Of Cooling-Drag In A Generic Passenger Car Using Cfd And Wind Tunnel, Md Maruf Hossain
Masters Theses
The focus of the study is to explore aerodynamic aspects of cooling airflow. As a result of this study, an efficient multi-domain aero-thermal model was developed to analyze the cooling drag of a generic passenger vehicle. Cooling drag is described as the additional force that the production vehicle has to overcome while moving in comparison to the force if all the openings were closed. Though this model was developed based on the sedan class vehicle, the applied methodology could be generalized for other ground vehicle types. As a part of the presented model, a unique simplified geometric model is developed …
