RISProposed Metric for Evaluation of Solar Forecasting Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents an alternative metric for evaluating the quality of solar forecasting models. Some conventional approaches use quantities such as the rootmeansquareerror (RMSE) and/or correlation coefficients to evaluate ...
Comparisons of Radiative Heat Transfer Calculations in a Jet Diffusion Flame Using Spherical Harmonics and k Distributions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new nongray radiation modeling library for combustion gases has been implemented in OpenFOAM. The spectral models for single species include gray, correlation tables and full spectrum kdistributions (FSK) assembled from ...
Spectral Photon Monte Carlo With Energy Splitting Across Phases for Gas–Particle Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In multiphase modeling of fluidized beds, pulverized coal combustors, spray combustors, etc., where different temperatures for gas and solid phases are considered, the governing equations result in separate energy equations ...
Forecasting of Global Horizontal Irradiance Using Sky Cover Indices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work discusses the relevance of three sky cover (SC) indices for solar radiation modeling and forecasting. The three indices are global in the sense that they integrate relevant information from the whole sky and thus ...
Implementation of High Order Spherical Harmonics Methods for Radiative Heat Transfer on openfoam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general formulation of the spherical harmonics (PN) methods was developed recently to expand the method to high orders of PN. The set of N(N + 1)/2 threedimensional secondorder elliptic PDEs formulation and their ...
