Abstract
Mixed convection in a horizontal channel loaded with discrete material and equipped with a top exhaust was studied experimentally and analyt ically. The steady how was two-dimensional 2D, while observed unsteady convection, triggered at a critical Richardson value, was highly thre e-dimensional 3D. Measured temperatures and those predicted with a 2D numerical model are in good agreement. The model, however, underestima tes the onset of the thermally-induced transition to unsteady convecti on.
