Similarity between Natural Wind in the Atmosphere and Model Wind in a Wind Tunnel (III)

Abstract

Applying the relation obtained in the similarity theory of turbulence, it has been already theoretically obtained in Part I that the relation _??_ would be approximately satisfied between the reduced scale of the wind velocity and that of the model as a condition of similarity, that is, practical and approximate modeling criterion for a local wind under the limited conditions. In the present paper, some experiments to which the above relation has been applied are described. iNemoto Vol . XII No.

Critical review of wind tunnel modeling of atmospheric heat dissipation

“…At high Reynolds number the flow is essentially independent of Reynolds number similarity. In a few studies attempts have been made to match the model and prototype turbulent Reynolds numbers and other turbulence parameters (Nemoto, 1961b, Orgill, 1971 . This type of model air flow has been used in wind tunnel studies since the pioneering efforts of Field and Warden (1929-30).…”

Problems of atmospheric shear flows and their laboratory simulation

“…Cermak et al [1] and Nemoto [51] have examined in detail the conditions for similarity of mean flow patterns and turbulence structure in topographical modeling. The non-dimensional parameters that are required to be matched are the Euler number, the Froude or Richardson number and the Reynolds number.…”
