  • Comparing the autoignition performance of chemical kinetic models for toluene using data extracted from the literature

    Creator:
    Mayer, Morgan
    Abstract:
    Real transportation fuels contain a wide range of hydrocarbon species, and this complexity poses challenges for modeling. Surrogates with a simpler blend of hydrocarbon reference fuels can approximate the physical and chemical characteristics of real fuels and enable practical simulation of the reacting flows that occur in engines and combustors....

  • Evaluating Stiffness Metrics for Predicting the Cost of Chemical Kinetics Integration

    Creator:
    Alferman, Andrew Thomas
    Abstract:
    Simulations of combustion and reacting flows often encounter stiffness in the equations governing chemical kinetics. Explicit solvers for these ordinary differential equations offer low computational expense, but typically cannot efficiently handle stiff systems. In contrast, implicit methods demand greater expense but offer unconditional stability—as a result, most reactive-flow solvers rely...

  • Electric Actuation of the Main Flight Valves of a Small Bi-Propellant Liquid Engine

    Creator:
    Edgerton, Jacob M.
    Abstract:
    The High Altitude Liquid Engine (HALE) team is developing of a 2000 lbf thrust liquid propellant engine for a flight vehicle capable of breaching the Karman Line (100 km in altitude). As part the development of this flight vehicle, this research focuses on the design and characterization of a novel...

  • Computational Investigation on the Effects of Arc Location in Vacuum Arc Remelting

    Creator:
    Soler, Miguel
    Abstract:
    Vacuum arc remelting (VAR) is a secondary melting process for exotic alloys. The main purpose of this process is to increase the input ingot’s physical and chemical homogeneity. This is accomplished through the application of a high current that melts the material through the emergence of electrical arcs that induce...

  • Swept time-space domain decomposition on GPUs and heterogeneous computing systems

    Creator:
    Magee, Daniel J.
    Abstract:
    Modern scientific and engineering problems often require simulations with a level of resolution difficult to achieve in reasonable amounts of time—even in effectively parallelized programs. Therefore, applications that exploit high performance computing (HPC) systems have become invaluable in academia and industry over the past two decades. Addressing the questions that...

  • Cooling System Analysis of the Thrust Chamber

    Creator:
    Sazonov, Gleb
    Abstract:
    The purpose of the study was to analyze the possible combination of cooling systems, which are film cooling and regenerative cooling, and obtain the initial estimates of possible temperature reduction. The analysis was conducted in Ansys Fluent. The methodology includes four main steps that are the following: flow simulation, combustion...

  • Soot Modeling: GPU Accelerated Direct Simulation Monte Carlo

    Creator:
    Lorson, Paige
    Abstract:
    For this project, we designed a soot modeling software to produce a full particle density function. This model uses the Direct Simulation Monte Carlo with a full conditioning particle selection method to capture soot nucleation and coagulation in a diffusion flame. We investigate the use of graphic processing units as...

  • An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

    Creator:
    Moore, Cailin J.
    Abstract:
    The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

  • The Mira 2 Rocket Engine: Applying Lessons Learned for an Improved Iteration

    Creator:
    Dimas-Harms, Colton R.
    Abstract:
    In this paper, I present the design of Mira 2, a small-scale, liquid bipropellant rocket engine, with a specific focus on its oxidizer-centered pintle injector. Building upon the valuable lessons and insights gained from the empirical testing of its predecessor, Mira 1, the Mira 2 engine incorporates several improvements and...
