Abstract

The nonsteady results of investigating the nonsteady heat-carrier mixing in bundles of spiral tubes with periodic variation in air flow rate by heat diffusion from a central group of electrically heated tubes are outlined. The frequency and amplitude of flow-rate oscillation influence the variation in heat-carrier temperature and effective turbulent-diffusion coefficient. The transition from steady thermal conditions to conditions with regular periodic variation in the temperature and the relative coefficient of heat-carrier mixing for the given type of nonsteady hydrodynamic conditions is considered.
