Multiphase flows play key roles in efficient working of many renewable energy devices. Efficient water management in polymer electrolyte fuel cells, wave energy extraction from oscillation water columns, or the prevention of hail damage of solar panels depend on our understanding of complex multiphase flows. Understanding all aspects of mass, momentum, and energy exchanges under different phases in dispersed and granular flows, liquid-gas, liquid-solid, gas-solid flows, flows in porous media, and boiling phenomenon are essential for efficient renewable energy generation. This Special Issue seeks to disseminate knowledge on various aspects of the modelling of multiphase flows relevant to renewable energy and promote multidisciplinary, fundamental, and applied research. This Special Issue aims to serve the research community by keeping them abreast of new developments in the modelling of multiphase flows relevant to renewable energy. This Special Issue covers but is not limited to the application of multiphase flows modelling in the following areas: Wave, tide, and ocean energies; Hydrogen production and fuel cells; Wind energy technologies; Solar photovoltaic and solar thermal applications; Biomass conversion; Desalination; Geothermal conversion; Desalination.
