Abstract
The flow between two concentric cylinders with the inner cylinder rotating with an imposed radial temperature gradient was studied using the digital particle image velocimetry method. Four models of a stationary outer cylinder without and with different numbers of slits (6, 9 and 18) were used. The Grashof number in this study was 1000. The results showed clearly that the buoyant force due to the temperature gradient caused the helical flow; this flow occurred when the Richardson number was larger than 0.0045. The constant temperature gradient considered in this research has little effect on the transition to a turbulent Taylor vortex flow in all models.
