| Abstract | ||||
| A new trend to a brine heater design with a sprayed saline water on horizontal tubes, where condensation takes place inside the tube bundle while the cooling evaporating film flows over the outside of the tubes. For the condensation inside and film evaporation outside the tube, the analysis of potion and energy equations with each boundary conditions and the laminar theory were undertaken. The resulting system of first order ordinary differential equations were solved numerically by computer program using Runge-Kutta-type method for a wide range of parameters. It was found from the numerical results that the heat transfer coefficients for the condensation and evaporation were inversly proportional to the film thickness around the tube. The average overall heat transfer coefficients increases by decreasing the saline water Reynolds number and the tube radius. | ||||
