Some remarks concerning recent work on rotating turbulence

Abstract

Some aspects of a recent paper on rotating turbulence by Canuto and Dubovikov [Phys. Fluids 9, 2132 (1997)] are examined from historical and scientific perspectives. Their claim to have discovered a new energy spectrum scaling law for rotating turbulence is examined in light of previous publications on this subject. We answer an objection raised to the consistency of this spectral scaling law with the Bardina-type dissipation rate transport equation derived from this law by two of the authors [Phys. Fluids 8, 3172 (1996)]. Finally, some difficulties with the alternative model for the dissipation rate transport equation proposed by Canuto and Dubovikov are described in both the weak and strong rotation limits. © 1998 American Institute of Physics.
