The.ability to pre.ise.y e.timate.the.void fraction of multiphase.flow in a pipe.is ve.y important in the.pe.role.m industry. In this pape., an approach base. on our pre.ious works is propose. for pre.icting the.void fraction inde.e.de.t of flow re.ime.and liquid phase.de.sity change. in gas–liquid two-phase.flows. Imple.e.te. te.hnique.is a combination of dual modality de.sitome.ry and multi-be.m gamma-ray atte.uation te.hnique.. The.de.e.tion syste. is comprise. of a single.e.e.gy fan be.m,two transmission de.e.tors, and one.scatte.ing de.e.tor. In this work, artificial ne.ral ne.work(ANN) was also imple.e.te. to pre.ict the.void fraction pe.ce.tage.inde.e.de.t of the.flow re.ime.and liquid phase.de.sity change.. Re.iste.e. counts in thre. de.e.tors and void fraction pe.ce.tage.we.e.utilize. as the.inputs and output of ANN, re.pe.tive.y. By applying the.propose. me.hodology, the.void fraction was e.timate. with a me.n re.ative.e.ror of le.s than just 1.2480%.
