An algorithm is presented to integrate nonlinear partial differential equations, which is particularly useful when accurate estimation of spatial derivatives is required. It is based on an analytic approximation method, referred to as distributed approximating functionals (DAF's), which can be used to estimate a function and a finite number of derivatives with a specified accuracy. As an applic...

Combustion of hydrocarbons with pure oxygen as oxidizer is used, e.g., in high-temperature processes such the partial oxidation (POX) to produce synthesis gas high purity. Due prevailing temperatures, active cooling required for many parts. For laboratory-scale experiments, dimensions key parts are too small conventional manufacturing processes. One example a burner plate especially developed P...

Since a large number of physical parameters influence the flame dynamics in a full scale gas turbine combustor, it is virtually impossible to develop physically correlated reduced order models for flame dynamics by directly studying these complex reacting flows. Even the Rijke tube combustor system, though comprising of a simple geometry and a flat flame, shows a strong nonlinear coupling betwe...
