Direct Contact Condensation (DCC) of steam and water is a common phenomenon in steam-related industries, where it utilized for its added merits rapid heat, mass momentum transfer rates. The present experimental research focused upon studying the underlying physics jet characteristics saturated via swirl- non-swirl flow nozzles into stagnant, subcooled, restricted geometry circular, horizontal pipe. Employing image processing technique, effects nozzle geometry, injection pressure, degree...
Direct contact condensation (DCC) has achieved a well-known significance because of exceptional reasons such as efficient heat and mass transfer characteristics. The current experimental investigation involves considering the steam cavity shape characteristics with varying pressure, when saturated is condensed into one-phase water atmosphere using converging-diverging (CD) nozzle. results indicate four different shapes jet (oscillatory, conical, ellipsoidal double expansion–contraction). It...
The steam–water direct contact condensation (DCC) process is commonly observed in various industries due to its fast heat and mass exchange characteristics. This study investigates steam plume characteristics by experimentally condensing the jet issuing from a swirled flow spray nozzle into stagnant subcooled water. On basis of high-speed imaging, effects water temperatures on cavity shape, length, maximum expansion ratio were explored. existence three distinct shapes (ellipsoidal, double...
The phenomenon of direct contact condensation (DCC) has an advantageous feature high heat, mass, and momentum transfer efficiencies hence is highly significant for various steam-related industries such as chemical nuclear industries. present work investigates the underlying physics steam plume shapes during steam–water DCC saturated injection into a subcooled water-filled restricted geometry. These experiments have been performed using orifice-type nozzle circular, horizontal pipe. To study...
