Effect of surface configurations and their aspect ratio on Thermal behavior of liquids flowing over a rotating surface.
Thermal performance of thin liquid films flowing over rotating surfaces highly depends on the surface configurations. To investigate this effect a series of experiments were performed using smooth, dimpled, and cross corrugated surfaces. It has been observed that dimpled and cross corrugated surfaces enhance mixing process by creating turbulence, reduce minimum wetting rate and avoid film break ups even for low flow rates thatultimately, intensify the process of heat transfer. To quantify the impact experimental data were analyzedwith respect to local and average heat transfer coefficients and Nusselt number. It is established that dimpled and corrugated surfaces significantly improve the thermal and hydrodynamic characteristics as compared to smooth surface. The liquid film on cross corrugated surfaces progressively improves mechanism of heat transfe
