An experimental investigation for the thermohydraulic of packed beds in the comparison with the computer code THERMIX-2D

Creators

Description

The computer code Thermix-2D is tested with regard to the formalism for the effective heat conductivity by experimental data. Especially the part of dispersion is investigated. In addition to the heated main stream a cooler gasstream is injected into the center of the packed bed. The thermal compensation is measured and calculated. (orig.)

Abstract (German)

Das Rechenprogramm Thermix-2D wird hinsichtlich des Ansatzes fuer die effektive Waermeleitfaehigkeit mit ueberwiegend dispersivem Anteil im Vergleich mit experimentellen Daten ueberprueft. Innerhalb einer Kugelschuettung wird einem stationaeren Heissgasstrom ein lokal eingeleiteter Kaltgasstrom (Straehne) ueberlagert und die thermischen Ausgleichsvorgaenge werden gemessen und gerechnet.
