摘　　要：Between 0.1 and 0.6 MPa, there are the experimelltal investigation and theoretical modelon void fraction of air-water two-phase in belieal-coiled tubes in this paper. According toexperimental datum, the correlation maps for adverge value of void fraction and volumetricvoid fraction in three different belieal-coiled tubes are achieved.By means of theoretical models, the correlation formulas for calculating the average void fraction of main flow patternsare obtained, the experimental results agree qualita tively with the calculated results.Between 0.1 and 0.6 MPa, there are the experimelltal investigation and theoretical modelon void fraction of air-water two-phase in belieal-coiled tubes in this paper.
