Abstract
The duct with a sharp 180-degree turn is widely used for heat exchanger. We present numerical calculations of flow and thermal fields in two-dimensional duct with a sharp turn. The effects of the Reynolds number on the characteristics of the flow and heat transfer are studied. At Re=1200 the flow has steady solution, then at Re=1300 the flow becomes unsteady and the pressure loss decreases.
