Abstract The work presents computational modeling and an experimental investigation of silica deposition occurring in geothermal systems with superheated steam flows. An advection diffusion model was implemented for predicting silica particle transport and deposition in turbulent flows. The model includes the effect of Brownian diffusion, turbulent diffusion, turbophoresis, Saffman lift force, and drag force on particle motion. Simulation results for deposition of silica particles in superheated...

The paper describes a computational study and an experimental investigation of aqueous potassium carbonate droplets in superheated steam flow for potential applications in mitigation of superheated geothermal steam. The computational model included the boiling point elevation due to the droplet salt concentration as well as other concentration-dependent physical properties of the salt solution. Various phenomena involved in the process, such as breakup, transport, heat transfer, boiling and coup...

Abstract A study on scrubbing of superheated steam containing silica impurities is performed using an aqueous potassium carbonate solution as a potential application in mitigation of superheated geothermal steam. An experimental setup aimed at testing a silica particle scrubbing technique was built. The setup consists of a superheated steam generating system, a silica particle feeding and an injection system, a salt solution injection and separation system, and a sampling unit. Silica particle c...
