The main factor that affects the efficiency of separation process is lack contact with surface shutter when moving in flow small droplets wet steam. This depends on physical and chemical properties vapor, dispersion droplets, parameters movement two-phase medium, adhesion edge angle, geometry channel. Purpose. Determination limit modes operation devices depending quantity droplet liquid, geomet...

For power upgrading VVER-440 reactors we need to know exactly how the temperature measured by the thermocouples is related to the average outlet temperature of the fuel assemblies. Accordingly, detailed knowledge on mixing process in the rod bundles and in the fuel assembly head have great importance. Here we study the hydrodynamics of rod bundles based on the results of direct numerical and la...
