RISRay Effect Mitigation Through Reference Frame Rotation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The discrete ordinates method is a popular and versatile technique for solving the radiative transport equation, a major drawback of which is the presence of ray effects. Mitigation of ray effects can yield significantly ...
On Multilayer Modeling of Radiative Transfer for Use With the Multisource k Distribution Method for Inhomogeneous Media
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonisothermal medium is modeled using the multilayer approach in which the continuous temperature distribution in a onedimensional system as modeled as being piecewise constant. This has been shown to provide accurate ...
Network Uncertainty Quantification for Analysis of MultiComponent Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to impact physical mechanical system design decisions and realize the full promise of highfidelity computational tools, simulation results must be integrated at the earliest stages of the design process. This is ...
Network Uncertainty Quantification for Analysis of Multi-Component Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to impact physical mechanical system design decisions and realize the full promise of high-fidelity computational tools, simulation results must be integrated at the earliest stages of the design process. This is ...
Accelerated Solution of Discrete Ordinates Approximation to the Boltzmann Transport Equation for a Gray Absorbing–Emitting Medium Via Model Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work applies a projection-based model-reduction approach to make high-order quadrature (HOQ) computationally feasible for the discrete ordinates approximation of the radiative transfer equation (RTE) for purely absorbing ...
Projection-Based Model Reduction for Coupled Conduction—Enclosure Radiation Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A projection-based reduced order model (pROM) methodology has been developed for transient heat transfer problems involving coupled conduction and enclosure radiation. The approach was demonstrated on two test problems of ...
