Fluid-modeling demonstration of good-engineering-practice stack height in complex terrain
A demonstration study using fluid modeling to determine the good-engineering-practice (GEP) stack height for a power-plant installation in complex terrain is discussed. The site chosen for this demonstration study was the Clinch River Power Plant in southwestern Virginia, and a 1:1920 scale model of surrounding terrain was constructed. Measurements are presented that describe the simulated atmospheric boundary-layer structure, plume-dispersion characteristics in that boundary layer, and the maximum ground-level concentration (glc) of effluent downstream from the source, both in the presence of all significant terrain surrounding the plant and in the absence of nearby upwind terrain. Analysis of the maximum glc showed that, in this case, a stack height of 326 m meets the current GEP criteria under 50% plant-load conditions, i.e., the nearby upwind terrain effected an increase of 40% in the maximum ground-level concentration.
