Zasyadko // Food and Environment Safety. – 2016. – Volume 15, Issue 3. – P. 284–298.https://dspace.nuft.edu.ua/handle/123456789/26068The result of heat transfer modeling in down flowing turbulent films with the developed wavy structure at the regime of evaporation from film interface at free falling and with co-current steam flow, a heat transfer model, which takes into account a cyclic process of temperature field relaxation with the periodic mixing of film by big waves, has been presented. Temperature profiles along with the integral heat transfer coefficients (HTC) were obtained as a result of approximate solutions of heat transfer differential equations of in turbulent flows, adapted thus film flux with large surface waves, utilizing turbulent transport model by M.
