Temperature and velocity characteristics of rotating turbulent boundary layers under non-isothermal conditions

This paper describes an experimental investigation, by means of hot-wire anemometry, the characteristics velocity and temperature in a rotating turbulent boundary layer under isothermal non-isothermal conditions. The ranges parameters are as follows: Reynolds number from 10 000 to 25 000, rotational speed 0 150 rpm, y+ 1.8 100. relative difference is held constant at 0.1. Detailed distributions measured state, new criterion for segmentation rotation proposed. applicability theory state extended. influence Coriolis force buoyancy on layers analyzed. found play important role behavior rotation, it shifts layers. Under conditions, such effects can be classified according dominant force: viscous, Coriolis, or inertial. occurs. induced suppresses effect force, suppression increases with difference. variation Prandtl Prt also obtained.
