Laminar And Turbulent Flow

We show clear experimental evidence that in the laminar flow regime, there is a continuous redistribution of population on different vibrorotational energy levels as the flow rate increases. Such redistribution comes to an abrupt stop when the flow changes to turbulence. The population distribution then remains almost unchanged even up to the flow rate 10 times the laminar to turbulent transition. The flow status of carbon dioxide is therefore closely related to its internal energy level population distribution.

The cascade process describing the energy loss and relaxation or multiplication of highly non-equilibrium secondary electrons and holes in crystalline platinum irradiated by lowenergy electrons is studied. The pair-creation scattering rates are evaluated in the framework of the statistical model taking into account the electron band structure of platinum. Kinetic equations for the excited electron and hole energy distributions are solved numerically in the isotropic scattering approximation for some primary (excitation) energies Ep which do not exceed the plasma energy.
