The principle of fluid flow in the tube side and shell side of a heat exchanger
Thread Content
In chemical production, there are many principles regarding the flow of fluids through the tube side and the shell side. For example: (1) Fluids that are difficult to clean and prone to scaling should flow through the tube side, as this facilitates cleaning; (2) Fluids with low flow rates and high viscosity should also flow through the tube side, since the tube side can be designed with multiple passes, allowing for higher flow velocities and thus an improved heat transfer coefficient; (3) Corrosive liquids should flow through the tube side, so as to prevent both the tube bundle and the shell from being corroded. Let’s discuss this and see if there are any additional points to add
High pressure is applied to the tube side to prevent pressure from being applied to the shell side.
For water-cooled condensers, the circulating water flows through the tube side； For those heated by steam, the steam generally flows through the shell layer ；
