Holographic interferometry has been used to study the heat transfer by freeconvection from horizontal elliptic cylinder.

The experimental results indicate that freeconvection caused by the buoyancy in the heated tube with natural circulation has great influence on the heat transfer characteristics.
As a result, heat dissipating capacity, metal thermal intensity and freeconvectionheat transfer coefficient of the longitudinal closed finned tube are higher than those of the open finned tube.
