静止流体中の回転円筒まわりの乱流せん断流 : 第2報, スペクトルテンソルによる乱れ場の考察

Spectrum tensor equations are derived for ψ2, 1, ψ2, 3, and ψ1, 3, and the roles of terms in the equations are studied. Some terms can be explained by the same concept of spectrum tensor (i=j), but others play different roles. The production terms depending upon Coriolis force and metric force occur, and they are not due to mean flow tensor. Particularly, the production terms appearing in equations for ψ2, 3 and ψ1, 3 have opposite functions. The role of pressure-velocity terms is transport of spectrum components. Viscosity terms perform destruction, and they are not dissipated into heat. ψ2, 1 is closely related to ψ1, 1, ψ2, 2 and ψ3, 3. The relationship between ψ2, 3, and ψ1, 3 is also close due to production terms.
