摘要

本文研究了纳米流体在透气截顶锥垂直旋转的诱导下,通过热量和积聚传输进行的混合对流倾注。研究考虑了对流型热边界条件和零纳米粒子质量通量条件。热泳和布朗运动的影响已被纳入本纳米流体模型。为了将耦合的非线性边界线片方程转化为无量纲偏微分方程,引入了一组非相似性变换。随后,利用光谱配位法和局部线性化技术对随后的偏微分方程进行数值计算。为了验证数值技术,将获得的结果与特定情况下的既定结论进行对比。此外,还讨论了纳米流体的切向速度和漩涡速度、温度、硬体积分数以及外部阻力、温度和积聚传输特性等各种体质约束条件对纳米流体的影响。

Effects of convective heating and suction/injection on mixed convective flow of a nanofluid over rotating truncated cone

This paper investigates the mixed convective pour of a nanofluid through warmth as well as accumulation transport induced by the vertical rotation of a permeable truncated cone. The study considers convective-type thermal boundary conditions and zero nanoparticle mass flux conditions. The effects of thermophoresis and Brownian motion have been integrated into the present nanofluid model. To transform the coupled non-linear border line sheet equations into dimensionless partial differential equations, a set of non-similarity transformations is introduced. The ensuing PDEs are then numerically figured out using a Spectral collocation method in conjunction with the local linearization technique. To authenticate the numerical technique, the obtained outcomes are in contrast to with established findings in a specific case. The manipulate of a variety of corporeal constraints inactive on the tangential and swirl velocities of the nanofluid, as well as warmth, hard volume fraction, as well as exterior drag, warmth, as well as accumulation transport characteristics, are discussed.

期刊介绍: Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
