It is shown that the flooding regime and hold up regime in internal flows occur at arbitrary values of velociries of gas flow. The quantitative dependence of the film thickness from the values of the Reynolds numbers for hold up of the gas hollow within an infinite rectilinear tube with a circular cross-section are obtained. The problem of heat transfer from an external heated medium into a straight channel with inserts of different geometries filled with a homogeneous viscous incompressible fluid is solved numerically in dimensionless form in the region of small Reynolds numbers Re. The quantitative dependence of the levels of heat flows through the boundaries of channels with inserts of different geometry (height, width, distance between inserts for symmetric and asymmetric followings) and the difference in pressure at the input and output of the rectilinear channel from the velocity of the laminar flow are obtained.
