Abstract Plate and Shell Heat Exchangers (PSHE) are vital in industries due to their
adaptability and efficiency. This study applied the finite element method to analyze PSHE
plate behavior, which is challenging to assess experimentally. The equivalent von Mises
stress field was determined for four-plate setups under different conditions: internal channel
pressure, external channel pressure, and pressure in both branches. Peak stresses were
found at corrugation tops during contact, varying stress levels based on operating …
