Investigation of hydrodynamic parameters distribution in heat exchange tubes of falling film evaporator

The purpose of this work is investigation of changes in hydrodynamic parameters (absolute pressure, mass flow rates of solution and secondary steam, secondary steam velocity, solution irrigation density, and pressure loss) along the length of the heat exchange tube of a vertical falling film evaporator. The obtained data of the distribution of hydrodynamic parameters were used in the design of falling film evaporators.
