Changing of energy dissipation in the transition of laminar flow to turbulence (rus)

Abstract

Under the same fixed dynamical boundary conditions the energy dissipation in laminar and turbulent flow are compared. As examples the flow past a plate and the flow through a pipe are considered. It is found out that in turbulent flow energy dissipation is essentially less than in laminar flow (under the same boundary dynamical conditions).
