description: The main objectives of this work are to calculate the flow at different parameters of the angle of the branch of the lateral channel and the distribution of flow along two branches, as well as to compare the obtained solution with experimental data. The paper presents the results of a study of laminar flow in the area of a branching channel of circular cross section, with an input Reynolds number Re = 240. Numerical simulation was carried out using the commercial code Ansys v.19.3. The flow analysis was carried out. The dependence of the solution on the spatial resolution and the type of computational grid is analyzed. The formation of recirculation zones on the outer walls of the channel, as well as Dean vortices in the cross section of the tee, is investigated. The influence of the channel branching angle and the fluid flow rate on the two branches of the channel on the length of the recirculation zones is analyzed.
