Abstract: To improve heat transfer efficiency, Horizontal Tube Thin Film (HTTF) evaporators are being used in multieffect desalination plants. These plants require less pumping energy than thermal-based desalination plants. To generate the design data, experimental studies were carried out in a single-tube HTTF experimental setup, and heat transfer correlations were developed at BARC. The experimental findings and results are presented and discussed in this paper.

Keywords: HTTF evaporators; thermal desalination; waste heat utilisation; heat transfer; horizontal tube thin film; low grade heat; seawater desalination.
