Extensive experiments have been carried out at an air-water loop to study the phase splitting characteristics of semi-annular flow in a new type distributor. The distributor composes eight small holes with a diameter of 3.5mm on the pipe wall and an annular chamber mounted outside of these holes. The gas-liquid mixture extracted from the holes is collected in the annular chamber and enters branch arm ultimately. Compared with conventional T-junction, the branch quality can maintain unchanged over a wide range of mass extraction rates. A model is developed to predict the phase separation in dividing semi-annular flow. The model simulation results were compared with experimental measurements, and there is reasonable agreement between model prediction and measured data. According to this model, the desired branch quality may be achieved by changing the ratio of gas flow area and liquid flow area.

The article discusses methods for determining the hydraulic resistance of units of an accident-resistant fuel system. A detailed description of the need to create such fuel systems for modern helicopters is given. The development of such systems today is impossible without the use of the method of mathematical modeling, which allows to qualitatively solve problems arising in the design process. To obtain accurate research results, it is necessary to have a complete description of all elements and assemblies of the system. Methods for determining the hydraulic characteristics of AFS elements using the drag coefficient, reference literature and CFD codes are considered. As the investigated AFS units, a drain valve and burst fitting were studied in the article. A hydraulic calculation of these AFS elements ware performed, the simulation results are presented in the ANSYS CFX software package. Also as the calculation results of bursting fitting, the pressure distribution fields of full and static pressure, velocity and streamlines are also shown. An experimental setup for validating the results obtained using the mathematical modeling method is considered, as well as a methodology for conducting a full-scale experiment to determine the hydraulic resistance of the unit. Materials have been prepared for inclusion in a one-dimensional mathematical model of an accident-resistant fuel system.
