Some questions about falling film evaporators
Thread Content
What are the appropriate flow rates for the tube side and shell side of a falling film evaporator? Does anyone with expertise know the answer? I would be extremely grateful
In actual production, it is checked through the viewing port to ensure that the liquid distributes evenly on the walls
If it’s not a full pipe, how can the flow rate be determined?
I am working on a course project, so I don’t have a physical setup. The heat exchange area is 85㎡ – what is the generally recommended flow rate?
The flow rate in the tube side is 0.5 meters per second, while the gas flow rate on the shell side is 30 meters per second at atmospheric pressure. For reference
Tube-type falling-film evaporators are generally designed with a tube length-to-diameter ratio of greater than 30. Pay attention to the evenness of the film application
Such device designs should have tables showing flow rates and similar information, right?
