DETERMINATION OF THE LIMITING FLOW RATE IN LIQUID FILMS FOR HEAT TRAHSFER CRISIS CALCULATION
Resumo
The dynamic stability of the liquid film of finite thickness flowing at the flat surface under the gas flow effect is investigated. Equations for the most critical wave length of viscous and inviscid liquid flows are obtained. Based on the results the experimental data on liquid film flow rates during the transition from the non-stalled to stalled flow induced by gas are generalized. The developed expression for the limiting flow rate in liquid films is valid for a wide range of liquid and gas properties.
