Numerical Determination of the Thermal Characteristics of a Heat Exchanger with Semicircular Tubes and Wavy Fins
The article describes the numerical simulations of a heat exchanger section with a bundle of eight semicircular tube, either plain or connected with longitudinal wavy fins of four different lengths. The inlet velocity ranged from 0.433 to 4.33 m/s (Re=1,000-10,000), with study focused on pressure drop, total heat trans...
