摘要: Abstract Local and average heat-transfer coefficients in water film evaporation on horizontal profile tubes were measured. Dependences for calculating the heat transfer are presented. The studies conducted demonstrated that use of longitudinally-profile makes it possible to increase, with an account development heat-exchange surface, from wall flowing-down liquid by a factor 1.35–1.85, overall “vaporliquid” transfer, 1.3–1.5. This allows such be recommended desalination plant evaporators.
