Resumo

Experiments have been performed to determine the dependence of the longitudinal vortex wavelength present in the transition flow regime adjacent to an upward facing inclined isothermal surface on the angle of surface inclination and surface to bulk temperature difference. An electrochemical technique was employed to visualize the vortices, and photographs enabled measurement of the wavelength. Angles of inclination investigated ranged from 20 to 60 degrees relative to the vertical, and the temperature differences ranged from 1.5°C to 37.6°C. The experiments reveal that the vortex wavelength depends upon the surface to bulk temperature difference but is independent of the surface inclination.
