Description
Accurate simulations of gas flow within pipeline networks provide crucial insights for transmission and design operators. This importance intensifies with the growing integration of hydrogen-blended fuels in hydrogen-based energy systems. Existing models predominantly address single-component, one-dimensional flow within individual pipe segments, interconnected at network junctions. Recently, composite flow models within pipes, frequently employing mixture fraction methods, have garnered significant attention. These methods utilize a segregated approach to flow and composite transport, albeit within the limitations of one-dimensional modeling. Physically, hydrogen's low molecular weight can lead to complex and non-intuitive flow dynamics and advection patterns in blended gas mixtures which may not reflect in 1D models. Exploring higher-dimensional models can offer a more comprehensive understanding of the underlying physics. The talk focuses on developing 2D and 3D pipe flow models for composite gases, explore coupling frameworks and numerical discretizations for networks.
