Falling Films in Desalination covers the simulation of evaporating seawater falling films with and without turbulence wires. It is intended especially for calculation engineers in process and chemical engineering. In these disciplines, the evaporation of the solvent of a solution is of great interest. The reader also finds advice on how to simulate this general case. Falling films are employed in numerous applications like in food industry, in pharmacy or in power plants. In times of global warming, seawater desalination can be essential in the production of potable water. This book presents fundamentals and guides through various steps, from the smooth film to the direct numerical simulation with the open source CFD software OpenFOAM. The benefit of turbulence wires, also known as tripping wires, is discussed as well.
