This is a critical safety feature. HTRI checks for flow-induced vibration (acoustic vibration, fluidelastic instability). A design that looks good thermally might rattle tubes to death; HTRI catches this instantly.
When running an HTRI simulation, the software generates messages to flag operational or structural risks. "Pressure Drop Exceeded" htri heat exchanger design top
: Keep values within allowable limits, typically 0.5 to 1.0 bar . While maximizing pressure drop can improve heat transfer coefficients, exceeding limits often signals an inefficient layout. This is a critical safety feature
Maintain a baffle cut between 20% and 35% of the shell diameter. htri heat exchanger design top
