Sound propagation in saturated gas-vapor-droplet suspensions considering the effect of transpiration on droplet evaporation

► We considered sound attenuation and dispersion in gas-vapor-droplet systems. ► We took into account the effect of transpiration on droplet evaporation. ► We extended the theory of Davidson (1975) for including transpiration. ► We validated the theory with the data of Cole and Dobbins (1971) for low droplet concentration. ► We demonstrated the importance of transpiration at both low and high droplet concentration.
