ABSTRACT Passive thermal management is an established and cost‐effective way of cooling electronic devices. This paper aims to investigate the potential heat transfer enhancement by combining influence cavity inclination angle twin fin orientation for air‐filled cavity. The SIMPLE algorithm used solve governing conservation equations, which are discretized using finite volume method. field internal fluid flow calculated a range Rayleigh numbers (10 4 ≤ Ra 5 × 10 ), (0° φ 60°), (−60° γ b positions (0.375 L 0.75, 0.25 0.625). Outcomes indicate that increasing number leads in intensity Furthermore, rate enhanced positively orienting fins optimal = 15°. Moreover, installing plate on upper part left hot sidewall improves characteristics. Combining shows enhancement, achieves its maximum 15° with positive orientations 60°. up 15.32% compared reference case. These findings can help design more efficient air‐based systems electronics as well other applications.

Abstract This study establishes a 3D steel roller shaft model to investigate the failure mechanism of and analyzes maximum stress point coating by applying loads in ABAQUS software based on real working conditions. The results show that under simulated conditions is at junction between large end small shaft, value 366 MPa, exceeding yield strength 45# steel. position same as damage failed factory, indicating correctness simulation analysis. At time, structural optimization analysis performed, service life optimized structure twice or even longer than original one, can significantly improve shaft.
