Abstracts:
Heat transfer in the laminar-wave liquid film on the heated inclined plate is studied numerically. The liquid free surface contacts to motionless gas, heat exchange between a liquid and gas is presented by Newton's law. The integral-boundary-layer model is applied to the describe the wavy film flow Calculations results demonstrate the effect of physical properties of a liquid (Prandtl number, Biot number) and wavy film flow parametres (Reynolds number, wave length) on an heat transfer intensification by steady travelling waves. |
