Numerical modelling of thermal conduction processes in the fins of two-stage “water to air” heat exchanger

In this paper numerical investigation by ABAQUS software of heat conduction processes in the fins of two-stage “water to air” heat exchange (HEx) apparatus. Temperature values of the processes in ducts, have been used as boundary conditions for accomplishment of the simulations in the heat exchanger’s fins. The coefficients of heat convection for the processes between the fins and the airflow calculated by temperature field in the fins. Processes have been studied in “cooling” and “heating” regimes. The values of the coefficients obtained on the basis of simulations and by criterion equations, are compared.
