Flow uniformity index formula
WebDescription. The surfaceFieldValue function object provides options to manipulate surface field data into derived forms, e.g. to report summations, averages and extrema; to calculate the volumetric or mass flux across a patch. Base operations: WebAn exemplary exhaust testing apparatus includes a housing defining an exhaust flow path extending from an inlet to an outlet. At least a portion of the housing is selectably rotatable relative to an exhaust aftertreatment system. An arm extends from the housing into the exhaust flow path. An exhaust probe configured to measure an exhaust constituent is …
