On the effective temperature concept for liquid: Paradox of the similarity?
Original language description
Vortex shedding behind a heated cylinder for diluted gasses can be solved by reducing to an isothermal case by the effective temperature Teff, with respect to the similarity condition ReC,=ReC,eff. Different situation occurs for liquids. Although the similarity should exist (cylinder cooling stabilizes wake), finding the value of c represents a serious experimental problem. A basic question remains: exists a similarity for liquids or not? This study revealed that the mentioned similarity does not existfor water. Moreover, more general statement sounds: if the kinematic viscosity of a fluid tends to fall as temperature increases the similarity does not exist.
