Evaluation of diphenyl and dowtherm-A`s thermal cross sections and their application to reactor calculation; Evaluacion de la seccion eficaz termica del difenil y dowtherm-A y su aplicacion al calculo de reactores

Abstract

This work applies a scattering synthetic approximation to represent diphenyl and dowtherm-A dispersion laws on typical ranges of interest regarding temperature. The present formalism is based on a previous model of benzene molecule formerly validated. The results obtained from diphenyl agree with laboratory measurements, but those regarding dowtherm-A present some variations with respect to the available information. The result of the application of this model to the measurements made in Wrenlingen (Switzerland) to measure the vacuum coefficient of the cells charasteristic of high conversion reactors, are also presented, experimentally simulating said vacuum using dowtherm-A instead of H{sub 2}O.

[Espanol] En este trabajo se aplica una aproximacion sintetica de scattering para representar las leyes de dispersion del difenil y dowtherm-A sobre rangos tipicos de interes en temperaturas. El presente formalismo esta basado en un modelo previo de la molecula de benceno, validado anteriormente. Los resultados calculados para difenil estan en buen acuerdo con numerosas mediciones mientras que para dowtherm-A presenta ciertas variaciones con respecto a la escasa informacion disponible. Se presenta tambien en este trabajo el resultado de la aplicacion de dicho modelo a las mediciones realizadas en Wrenlingen (Suiza) para medir el coeficiente de vacio de las celdas caracteristicas  More>>
