description |
In the present work, the use of the passive heat transfer enhancement technique through surface
alteration was explored. The enhancement was achieved through internal conduit surface microgrooving using a new apparatus that was developed by modifying a Magnetic Abrasive Finishing
technique. A new surface profile was created and later verified using optical and laser profiler
measurement. The new profile was investigated numerically to compare the heat transfer and
hydrodynamic performance against other profiles that have been studied in the literature. It was found
from the results that the new profile shows much higher heat transfer improvement and comparable
pressure loss to the previously investigated profiles (i.e. square, rectangular, trapezoidal and circular).
Overall, the new groove geometry provides the highest performance followed by the circular, triangular,
curvy, square and rectangular grooves. Also, the results indicate that designs with a smooth profile
performs better than those with sharp edges, owing to the elimination of stationary fluid spots within
the grooves. The effectiveness between the profiles was compared based on the level of heat transfer
enhancement against the flow penalty. Experimental validation was further conducted for the
experimentally generated groove. The results revealed that a relatively small surface temperature drop
was obtained, corresponding to a slight improvement in heat transfer. This confirms the results
generated by the simulation that groove size plays a major role in attaining significant improvement in
heat transfer |
