Abstract

Abstract

The spalling of oxide scales formed on the inner surface of printed circuit heat exchanger (PCHE) seriously influences the safe and efficient operation of supercritical CO₂ Brayton cycle units. The existing prediction model for spalling is difficult to make accurate prediction because it lacks the key parameter of shear failure strength of oxide scale. To address this issue, an analytical model for the evolution of interfacial shear stress under tensile loading was established based on the assumption of elastic-linear hardening mechanics for the transition layer at the oxide scale/substrate interface. Then, a new method for measuring the shear failure strength of the oxide scale was proposed, which involved tensile loading tests combined with acoustic emission technology and specimens with oxide scales. The results indicate that the proposed method accurately predicts the evolution of shear stress at the oxide scale/substrate interface and determines the shear failure strength of the oxide scale without making any prior assumptions about the interfacial shear stress distribution. This method can provide key data for constructing the criterion and prediction model of oxide scale spalling on the inner surface of supercritical CO₂PCHE.
