Abstract：By using heat transfer experimental methods designed by ourselves, high accuracy thermo-resistance and computer data acquisition system, the law of dynamic change of salt-out layer at different main flow temperatures and velocities are studied. Experimental results show that main flow temperature has a deep effect on salt-out of salt solution when the average main flow velocity is constant. It means that occurrence and development of salt-out are slow at high temperatures and their differences increase as time goes on. The increasing rate of salt-out layer thermo-resistance is high at low velocity when the main flow temperature is constant. The tendency of the dynamic change of salt-out layer thermo-resistance increases linearly at different main flow temperatures and average velocities. The experimental method and resuhs provide references for studying the mechanism of dynamic salt-out.
