AN UPGRADED VISCOUS COUPLING MEASUREMENT METHODOLOGY

Suggestions are presented in this Note about simple but usually ignore d ways to enhance the reliability and utility of the otherwise interes ting procedures recently studied (e.g. by Zarcone and Lenormand and in dependently by Dullien and Dong) for obtaining needed information abou t the relative importance of the role played by viscous coupling pheno mena during multiphase flow processes that occur in and through the in terstices of natural porous media systems. This is done now because of the persistence of so many perplexing questions and contradicting opi nions about what has been a controversial subject ever since the appea rance of Yuster's watershed paper in 1951. Here, the belief herd by at least a few of the currently publishing authorities is embraced, name ly that viscous coupling issues will never be fully settled until the indications of the underlying theoretical interpretations can be fully confirmed by laboratory observations, hence a disclosure of even mode st ways to achieve data acquisition enhancements is the motivation for what is written in what follows.
