In this study thermal performance of corrugated plate heat exchanger (PHE) in single-phase flow is carried out using the ANSYS CFX software. Aim of this research is to develop a generalized Nusselt Number correlation for a commercial PHE configuration under single-phase flow for two different chevron angle plates, 30 o /30 o and 60 o /60 o . The steady state simulation is carried out for a Reynolds number range of 500 to 2500, and the Prandtl number range of 3.5 to 7.5 is maintained in the simulation. The results showed that Nusselt number is increased with increasing Reynolds number as well as by increasing the chevron angle. However, Prandtl number showed trivial impact on the Nusselt number.

Structures in real-life scenarios like industrial robots, spaceships, aircrafts, submarines, bridges, and pressure vessels undergo different loading conditions. These structures are prone to damage due to the risks related to fatigue and aging. Small cracks may appear in these complex structures and prove to be fatal. These cracks may open and close, hence termed as breathing cracks, exhibiting nonlinear behavior under load. Various nonlinear techniques exist
