Introduction to Multiphase Flow Measurement Techniques

Multiphase flows—where gases, liquids, and solids interact—are foundational to industries ranging from energy production to chemical processing, yet measuring their properties accurately presents a unique engineering challenge. This text-only course provides a clear, step-by-step introduction to the essential instrumentation and diagnostic methods used to analyze these complex systems. You will start with foundational fluid dynamics concepts and terminology before exploring various measurement technologies. Through structured written explanations, analytical breakdowns, and practical application scenarios, you will learn how to select, configure, and evaluate the right measurement techniques for different flow regimes. What you'll learn: - Understand the fundamental characteristics of multiphase flow regimes and phase fractions. - Explore intrusive measurement methods, including pressure-based sensors and electrical impedance probes. - Study non-intrusive diagnostic techniques such as laser Doppler anemometry and modern tomographic imaging. - Analyze velocity and flow rate measurements in liquid-gas, solid-liquid, and three-phase flows. - Learn how to interpret experimental flow data and handle measurement uncertainties. - Evaluate the selection criteria, limitations, and calibration requirements for various industrial sensors. The course begins with basic definitions and classification of flow regimes, building systematically toward advanced optical diagnostics and data analysis. This course is designed for engineering students, technicians, and researchers looking for a solid foundation in fluid diagnostics, with no advanced prior experience in multiphase flows required.
