phase change from liquid to gasLogin
liquid velocity is harmful to the gas take-off.Whereas at vertically upward inlet tube and annular flow,the liquid is mainly subjected to centrifugal force,and thus the liquid preferentially takes off from the branch.Increasing gas or liquid velocity is beneficial to the liquid take-off.In the ...
Modeling Study of Three-Phase Low Liquid Loading Flow in Horizontal Pipes A mechanistic model is proposed to predict flow characteristics of three-phase stratified wavy flow in pipeline. For the gas-liquid interactions, Watson's ... H Karami,E Pereyra,C Torres,... - 《International Journal of...
If porous wall film removal devices are employed, it is noted that the momentum of the liquid in the huge waves could carry them past the device and that liquid would not be sucked off so giving an over large value of entrained fraction. Another possible technique is to utilise Phase ...
On the other hand, the main disadvantage observed when using SLM is the problem of low stability of the liquid phase in the pores. Higher stability has been achieved by using ionic liquids to impregnate the pores of a membrane, leading to supported ionic liquid membranes (SILM). Several ...
The liquid velocities and gas holdups in the riser and downcomer of three-phase internal-loop airlift reactors with Newtonian and non-Newtonian fluids were studied. The reactor was constructed of 19 cm ID Plexiglas column and 250 cm in height. The inside diameters of the draft tube were 9,...
Based on a laser diode, a 12 × 6 photodiode array sensor, and machine learning techniques, a new void fraction measurement method for gas-liquid two-phase flow in small channels is proposed. To overcome the influence of flow pattern on the void fraction measurement, the flow pattern of the...
phase: pre-cooling (vapor), condensation (phase change), and sub-cooling (liquid). The specific heat has a sharp peak around 200K, which makes the cooling load uneven along the NG flow. In order to achieve a high thermodynamic efficiency, it is crucial to minimize the entropy generation ...
The temperature and pressure at which agas mixturebegins condensing to form aliquid phase; for a fixed composition, the point is reached by lowering the temperature or increasing the pressure except when the mixture exhibits retrograde condensation. ...
Influence of liquid viscosity and surface tension on the gas-liquid mass transfer coefficient for solid foam packings in co-current two-phase flow The mass transfer coefficient and other hydrodynamic parameters are presented for a gas and liquid (air–water system) moving in a co-current upflow ...
