A COMPUTATIONAL WORKBENCH ENVIRONMENT FOR VIRTUAL POWER PLANT SIMULATION

This is the eighth Quarterly Technical Report for DOE Cooperative Agreement No: DE-FC26-00NT41047. The goal of the project is to develop and demonstrate a computational workbench for simulating the performance of Vision 21 Power Plant Systems. Within the last quarter, good progress has been made on all aspects of the project. Calculations for a full Vision 21 plant configuration have been performed for two coal types and two gasifier types. Good agreement with DOE computed values has been obtained for the Vision 21 configuration under ''baseline'' conditions. Additional model verification has been performed for the flowing slag model that has been implemented into the CFD based gasifier model. Comparisons for the slag, wall and syngas conditions predicted by our model versus values from predictive models that have been published by other researchers show good agreement. The software infrastructure of the Vision 21 workbench has been modified to use a recently released, upgraded version of SCIRun
