Rotating tumblers are used in a wide variety of industrial applications from mixing anddeburring to flow regulation and storage. Almost all model tumblers previously analyzed,both theoretically and experimentally, had circular cross sections that produced consistentflowing layer dimensions and steady state flow. In contrast, tumblers with triangular crosssections produced unsteady flow as a direct result of the dynamic dimensions of the flowingsurface. Although unsteady, the flow produced in triangular tumblers is periodic every 120◦of rotation after an initial mixing period. The mechanisms by which the flow characteristicsvary as a triangular tumbler rotates and the number of tumbler walls in contact with theflowing layer change, is poorly understood. The primary objective of this work is to determinethe effect of orientation, fill level, and tumbler size on flow velocities and flowing layerdimensions. High speed imaging with particle tracking velocimetry is the basis for theexperimental data collection. Results indicate that fill level has a dominating effect on thevelocity profile while tumbler size has a dominating effect on flow dimensions and velocityamplitudes. Normalization of various flow characteristics reveals a phase shift relation forvelocity as a function of tumbler orientation as both fill level and tumbler dimension change.
