Alternative methods for diagnosing the flow regime in a bubble column

Mostrar todas las versiones(2)

An alternative method that can help identification of the flow regime in a bubble column using a non-invasive methodology is proposed. It is based on the analysis of the time series of the number of photon counts emitted by a radioactive source that are able to cross part of the gas-liquid emulsion...
