Abstract

In the present work attempts were made to investigate the hydrodynamics and
heat transfer characteristics of tube-in-tube helical heat exchanger. The steady state
simulation was carried out in counter current mode operation with hot fluid in the tube
side and cold fluid in the annulus area. A commercial Computational Fluid Dynamics
package was used to predict the flow and thermal development in tube-in-tube helical heat
exchanger. CFD simulations are carried out in tube in tube helical coils by varying
different geometric parameters such as helical tube pitch.
