Effect of intermittency on thickness and heat transfer of turbulent falling liquid film

Research output: Contribution to journalArticlepeer-review

Abstract

A model for calculating the thickness and heat transfer of a turbulent film moving under the action of gravity and the shear stress of friction of a gas flow is constructed. The aim of this work is to supplement the previously proposed simple model of turbulent viscosity using a cubic law of damping in a viscous sublayer and a logarithmic asymptotic velocity far from the wall with additional linear damping near the free surface and to take into account the damping of turbulent transfer caused by intermittency of turbulence in flowing wave films of liquid.
