The determination of the maximum instantaneous pressure resulting from a sudden event within a heat exchanger is crucial for ensuring its structural integrity. This pressure peak arises from rapid changes in flow rates or valve closures, leading to a dynamic pressure wave that propagates through the system. Accurately quantifying this pressure spike allows engineers to design heat exchangers capable of withstanding these transient forces without failure. As an example, a quick valve shutdown upstream of a heat exchanger can cause a water hammer effect, creating a pressure surge significantly higher than the normal operating pressure.
Assessing this pressure phenomenon is paramount to preventing catastrophic equipment failures, minimizing downtime, and ensuring the safe operation of industrial processes. Overlooking this design consideration can lead to tube rupture, shell deformation, or other forms of mechanical damage, resulting in costly repairs, production interruptions, and potential safety hazards. Historically, inadequate consideration of these transient pressures has contributed to numerous industrial accidents, highlighting the necessity of robust analytical and design practices.
