Abstract
A method and a control unit for evaluating lifting force of a gas phase of a substantially vertical upward two-phase flow of a first fluid in a heat exchanger. The first fluid comprises the gas phase and a liquid phase. The method comprises determining that the lifting force of the gas phase is insufficient for lifting the liquid phase based on hot end approach of the heat exchanger and/or on pressure drop of the first fluid over the heat exchanger. The control unit is configured to determine that the lifting force of the gas phase is insufficient for lifting the liquid phase based on hot end approach of the heat exchanger and/or on pressure drop of the first fluid over the heat exchanger. A heat exchanger assembly comprising a heat exchanger and the control unit.
