摘要：
The paper presents the results of simulating the flow dynamics, friction, and heat transfer in a downward gas-liquid flow in a pipe. The mathematical model is based on the use of the Euler description for both phases. We have studied the influence of the change bubble size of the gas phase at the inlet, the gas volumetric flow rate ratio, and the initial temperature of the liquid and its velocity on the friction and heat transfer in a two-phase flow. The addition of the gas phase causes an increase in heat transfer and friction on the wall; as well, these effects become more noticeable with increasing void fraction and bubble diameter.
