This monograph presents a comprehensive study of dynamic gas-liquid dissolution as a new method for improving the performance and environmental efficiency of hydrocarbon fuels. It explains the physical and chemical mechanisms that allow combustible gases to dissolve in liquid fuels under non-equilibrium hydrodynamic conditions. The work describes reactor design experimental validation and engine tests demonstrating increased combustion efficiency and reduced emissions. Combining thermodynamics fluid dynamics and engineering innovation the book introduces a scalable technology for cleaner and more efficient energy systems.
