Geometric criteria for a one-shot gamma densitometer in multiphase flow

PDF Version Also Available for Download.

Description

In order to be able to provide fast and accurate void fraction data acquisition during the investigation of post dryout two phase down flow, it was determined that a gamma densitometer was needed in order to meet sensitivity requirements of the inverted flow experiments. Furthermore, because of the physical restrictions of the experimental apparatus, a multi-beam device could not be installed. By investigating some of the historic design problems of ``One-Shot`` devices, a new error minimization method was established using simplified transport theory which provides accuracy as good as the multi-beam devices. In this paper, a validation of the geometry ... continued below

In this paper, a validation of the geometry criteria was provided by comparing a numerical simulation against previous experimental work.
