Investigation on Thermal Boundary Layer Around Heated Spinning Cone by Using 3D-Holographic Interferometry
The convective flow around a heated rotating cone of finite length is investigated experimentally by means of 3D and realtime holographic interferometry at rotational speeds up to 4600 rpm and rotational angles from 0 to 90. This advanced optical technique allows visualization of the thermal boundar...

| description | The convective flow around a heated rotating cone of finite length is investigated experimentally by means of 3D and realtime holographic interferometry at rotational speeds up to 4600 rpm and rotational angles from 0 to 90. This advanced optical technique allows visualization of the thermal boundary layer. It's unstable transition region and the turbulent zones, as well as providing a detailed visual analysis of the holographic fringe patterns. Information about the thickness of the thermal boundary layer, and a new method for detecting and determining the critical points and critcal Reynolds numbers of the transition region. The results are compared with previously obtained experimental data. (Author)
