Abstract: | The mathematical model for determination of boiling expectation time and total local evaporation in the falling wavy liquid films at unsteady heat release has been developed. Numerical simulation of the process of wave formation in the falling films of liquid nitrogen has been carried out. Dependence of boiling expectation time on heat flux density under the conditions of graduated heat load increase has been calculated. Satisfactory agreement between the results of numerical simulations and experimental data is shown. |
