摘要：

Numerical simulation of gas bubble in a heated capillary tube at a constant pressure drop has been carried out. A significant increase of flow velocity is shown when taking into account the dependence of water viscosity on temperature. At the same time, a significant change in temperature on the heated wall was revealed. Unstable motion of the gas bubble is found in the case of variable viscosity. The mechanism of heat transfer during the movement of the bubble in the heated part of the capillary tube is described. The local values of the Nusselt number and friction on the wall are calculated.
