On the influence of the aspect ratio on structure formation in turbulent mixed convection
Abstract eng: Mixed convection in a cuboidal convection cell is studied under variation of the aspect ratio TXZ = L/H in the range 0.2 S TXZ S 4 at Pr z 0.7, Re z 8.6-103, Ra z 24108 and Ar z 4.5 by temperature measurements at certain locations. It is shown that the evaluation of dipole moments from the local temperatures leads to a quantity, which possibly indicates the formation of large-scale structures. Further it is found, that the number of convection rolls, which are formed in the sample, is less or equal in mixed convection as compared to pure thermal convection for all investigated FXZ.
