<Para ID="Par1">We consider parameter optimization problems which are subject to constraints given by parametrized partial differential equations. Discretizing this problem may lead to a large-scale optimization problem which can hardly be solved rapidly. In order to accelerate the process of parameter...</para>

The construction of reduced-order models for parametrized partial differential systems using proper orthogonal decomposition (POD) is based on the information of the so-called snapshots. These provide the spatial distribution of the nonlinear system at discrete parameter and/or time instances....

Oxy-fuel combustion, particularly using an integrated oxygen ion transport membrane (ITM), is a thermodynamically attractive concept that seeks to mitigate the penalties associated with CO2 capture from power plants. Oxygen separation in an ITM system consists of many distinct physical...

In order to design ITM-based oxy-combustion power cycles, various reactor engineering analyses must be conducted with detailed modeling and simulation. An intermediate-fidelity ITM model is used to explore the dependence of ITM performance on reactor geometric structure, flow configuration,...
