A NEW PRESSURE LOSS CALCULATION MODEL FOR OIL-WATER COMPLEX MIXING PIPE FLOW PATTERN

摘要

Based on the forming process and pressure loss characteristic of complex mixing flow pattern in experiment, such as W/O&W and O/W&W etc, a new pressure loss calculation model has been built. Flow pattern transition restriction was introduced into the model for the first time, so that equations of model can be solved theoretically and efficiently. The prediction results of the model was proved to be consistent with experimental data, and the modeling error was also analyzed.
