During the experimental study of two-phase flow regimes of carbon dioxide in the systems of temperature stabilization of frozen soils, the condenser to evaporator flow pulsations were recorded under thermal loads on the evaporator below 2 kW (6.58 W/m). Results of the data processing for investigated pulsation modes allowed to determine the thermal boundary load at which the coolant pulsations at the condenser outlet are terminated.

Key words: Two-phase flow, carbon dioxide, horizontal evaporator system, simulation
