  1. Development of Adaptive Closure Models for Large Eddy Simulations of Lean Blow-Out Conditions

    SBC: CFD Research Corporation            Topic: AF16AT14

    The objective of the proposed Phase II effort is to establish fundamental understanding of combustion-physical mechanisms leading to blowout, the critical evaluation of model limitations in predicting these blowout processes and the development of an improved combustion model to enable the prediction of lean blowout (LBO) in swirl-stabilized combustors. For this, high-resolution numerical simulati ...

  2. Measurement and Modeling of Surface Coking in Fuel-Film Cooled Liquid Rocket Engines

    SBC: CFD Research Corporation            Topic: AF15AT21

    Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of problems and challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal and/or catalytic cracking of hydrocarbon fuels is always accompanied with coke formation. Coke deposits on combustor and nozzle walls reduce heat ...

  4. Computational Model for Electrode Erosion by High-Pressure Moving Arcs

    SBC: CFD Research Corporation            Topic: AF11BT25

    ABSTRACT: The goal of this project is to develop theoretical models for electrode erosion in high-pressure arcs and incorporate them into computational tools for simulations of arc heaters. The complexity of the electrode material removal process is associated with the multi-phase nature of the arc-electrode interactions, melting and vaporization of the electrodes near the arc foot. Available mod ...

  5. A General-Purpose Software Tool for Multi-disciplinary Simulation Data Management and Learning

    SBC: CFD Research Corporation            Topic: AF11BT27

    ABSTRACT: The overall goal of the proposed effort is to develop and demonstrate a general-purpose, fast, and reliable management and learning software tool for analyzing massive data sets generated by dynamic multi-disciplinary simulation. In Phase I, key technology elements were developed and proof-of-principle was successfully demonstrated. Data management software encapsulating salient feature ...
