Element Potential-Based Procedure for Metamodeling of Combustion Products

摘要

A procedure for generating metamodels for calculating composition and properties from chemical equilibrium of reacting mixtures is presented. The procedure is novel because, in theory, it allows prediction of equilibrium quantities independently of the fuel and mixture parameters, such as equivalence ratio or fuel-air ratio. The resulting surrogates may find direct use in the analysis of thermodynamic cycles and the computations of flowfields requiring properties of combustion products. The present approach is justified by the formulation of the method of element potentials, a class of methods for the solution of chemical equilibrium problems.
