摘要:
本文深入探讨了受限渐扩射流内二维不可压缩层流的数值研究。该研究旨在了解入口开度比和雷诺数的变化如何影响传热和流动模式。研究采用有限体积法结合同位网格来求解控制方程。在广泛的入口开度比(0.2、0.4和0.6)和雷诺数(500至900)范围内,结果表明,增加渐扩通道中射流的入口开度比可使传热显著提高53%,同时将压力损失降低90%。这一结果有望通过减少所需的泵送功率来节约能源。值得注意的是,本研究具有开创性,为通过利用渐扩通道来强化传热提供了新颖且有价值的见解。
英文摘要:
This article delves into a numerical exploration of two-dimensional, incompressible, laminar flow within a confined diverging jet. The study aims to understand how variations in the inlet opening fraction and Reynolds number affect the heat transfer and flow patterns. The research employs the finite volume method with a collocated mesh to solve the governing equations. Across a broad spectrum of inlet opening fractions (0.2, 0.4, and 0.6) and Reynolds numbers (ranging from 500 to 900), the findings reveal that increasing the inlet opening fraction of the jet in the diverging channel can lead to a remarkable (53%) improvement in heat transfer while simultaneously reducing pressure loss by 90%. This outcome holds the potential to conserve energy by requiring less pumping power. Notably, this investigation is pioneering and offers novel and valuable insights into enhancing heat transfer through the utilization of a diverging channel.
