Abstract

Nowadays, wet gas flow rate measurement is still a challengefor experimental investigators and it is becoming an even moreimportant issue to overcome in the turbomachinery sector aswell, due to the increasing trend of wet compressionapplications in industry. The requirement to determine gasturbine performance when processing a wet gas leads to theneed to understand certain phenomena, such as type of liquidflow re-distribution, and errors introduced when the mass flowrate measurement of a two-phase gas is attempted.Unfortunately, this measurement is often affected by thepresence of liquid. Literature does not offer a unique definitionof the term wet gas, although it is recognized that a wet gas cangenerally be defined as a two-phase gas in which the liquidpercentage is lower than the gas one. This paper aims to collectand describe the main works present in literature in order toclarify i) the most used parameters that describe the types of wetgas, and ii) the types of errors and flow patterns which occur indifferent types of applications, in terms of pressure, percentageof liquid, Reynolds number, etc. Therefore, this literaturereview offers a comprehensive description of the possibleeffects of liquid presence in a wet gas and, and an in-depthanalysis of the limitations and beneficial effects of currentsingle-phase flow rate sensors in order to identify the bestsolutions, and empirical corrections available in literature toovercome this challenge.
