Numerical and Experimental Investigation of Supersonic Binary Fluid Ejector Performance

Ejectors are simple mechanical devices with no moving parts which convert the pressure energy of a motive fluid to kinetic and generate suction secondary fluid. The ability recover waste heat, operate using solar power use geothermal make ejector-based systems attractive in different industrial applications. main challenge refrigeration is their relatively low coefficient performance (COP). In order increase ejector performance, two chemically distinct fluids can be used cycle. It suggested that higher molecular mass for improve entrainment ratio binary (BFE) thus system COP. Inert gas combinations argon–helium krypton–air studied this paper computational dynamics (CFDs) experimental measurements. All CFD cases were axisymmetric appropriate turbulence model was selected based on validation. Specifically, static along wall measured validate predictions. found molar significantly compared krypton–air. measurements wall, addition, exhibited good agreement results obtained via (CFDs).
