论文摘要

T-junction is widely used in the marine engineering equipment, which will be in a rolling motion state during operation. The additional inertia force generated by rolling motion can cause unstable ffuid ffow and a strong thermal mixing inside the T-junction, increasing the thermal fatigue damage of the pipeline. An experimental study was conducted to investigate the thermal mixing characteristics in the T-junction under static and rolling motion conditions by Two-Color Planar Laser-Induced Fluorescence (TC-PLIF) technique. The main ffuid Reynolds number (Rem), inffow rate ratio (R), and rolling Reynolds number (Rer) range from Rem = 2110 to 15,850, R = 1 to 20, and Rer = 0 to 3520, respectively. The results show that the rolling motion causes the branch jet to sweep up and down in the T-junction, and the vortex structure is periodically generated in the temperature shear layer, which promotes the thermal mixing of cold and hot ffuids and increases the ffuid temperature ffuctuation. At the same time, the jet sweeping phenomenon caused by the rolling motion makes the leading edge and trailing edge shear layers bifurcate and recombine into two pairs of temperature shear layers, which expands the range of thermal mixing and makes the average temperature distribution more uniform than that under static condition. The inffuence of rolling motion on the temperature ffeld could be decreased with the decrease of Rer and/or R, as well as the increase of Rem. Additionally, the mathematical equations of the mean jet trajectory suitable for the thermal mixing of cold and hot ffuids in a T-junction under static and rolling motion conditions are established. The research results are expected to provide theoretical basis and technical support for pipeline design under rolling motion conditions.
