摘要: To check multiple states, pressure drops and liquid holdups were measured for gas (air)-liquid (aqueous solution) upflow downflow modes by changing flow rates at constant rate. The viscosities of varied adding propylene glycol in water. Also, single-phase (air or aqueous to test the modified Ergun equation (Macdonald et al., 1979)
