摘要: A model is developed to predict the evaporative heat transfer coefficient in a horizontal tube-falling evaporator and has been applied evaluate overall performance of desalination unit. Performance variation with different parameters like operation temperature, type water distribution system, mass flow rate distilled inside exchanger are analyzed. It observed that able trends characteristics reasonably well. However, at low liquid film conditions, overpredicts marginally. In order improve performance, it preheating before injection into desirable. Calculations also performed estimate value for typical
