Numerical Modeling of Heat Transfer and Hydrodynamics in Compact Shifted Arrangement Small ...

Numerical modeling of heat and hydrodynamics processes in the chaels of compact small diameter tube bundles with different transverse shifted arrangement is carried out. The fields of velocities, temperatures and pressures in the tube bundle chaels were obtained and their influence on heat transfer conditions and hydraulic losses were analyzed. The calculation of the thermohydraulic efficiency for different constructions of the tube bundles had been carried out and their results with data of well-known tube bundles of different geometry are compared.
