Numerical characterization of multi-nozzle spray cooling
This work aims to study the characteristics of multi-nozzle spray cooling using CFD method based on the fundamentals of air flow and liquid droplet collision dynamics. A mathematical model for the two-phase flow was presented. The simulations were performed using a EulerianeLagrangian approach. Focus was placed on revealing the flow behavior with multiple nozzles, the droplet trajectory, and th...
متن کاملNumerical and Analytical Study of Natural Dry Cooling Tower in a Steam Power Plant
Design of a natural dry cooling tower has been accomplished in two sections: the design of heat exchangers and the numerical solution of flow through the tower. Heat exchanger (Heller type) has been simulated thermodynamically and then coupled with a computer program, which calculated the turbulent natural convection flow through the tower. The computer program developed for this purpose can be...

متن کاملSnowfall observations from natural-draft cooling tower plumes.
During the winter of 1975-1976, snowfall from the plumes of large natural-draft cooling towers of power plants has been observed. Snow accumulations up to 2.5 centimeters have been found on the ground at extended distances from the cooling towers, and visibility has been restricted to less than 1600 meters in the tower plume near ground level.
متن کاملSimulation of Cold Spray Nozzle Accompanying a Water-cooling Adjustment
Cold spraying is a coating process which enables production of metallic and metallic ceramic coatings with dense (very low porosity level) and pure (low oxygen content) structures. Several coating applications such as corrosion resistance and electrical conductivity rely on these properties. Generally, cold spraying is based on higher particle velocities and lower process temperatures than othe...
