Consequence analysis for ISC-PRIME. Final report

Technical Report ·
OSTI ID:658806

Aerodynamic building downwash is a phenomenon caused by eddies created by air movement around building obstacles. Through the use of the Industrial Source Complex (ISCST3) model, EPA modeling guidelines have incorporated these effects in ground-level concentration calculations. In 1992, the Electric Power Research Institute (EPRI) decided to embark upon a program (project PRIME: Plume Rise Model Enhancements) to design a new downwash model to correct the deficiencies in the ISCST3 model. The resulting downwash module, PRIME, has been installed in the ISCST3 model as a replacement for the current algorithm; the resulting model is referred to as ISC-PRIME. This report describes the design of the model test runs involved and provides a summary of the results with comments on the differences between the two models.
