The present speculative investigation is concentrated to analyze the entropy generation and heat transfer phenomena in ciliary induced peristalsis of blood with the suspension of hybrid nanoparticles in a tube with heat source impact. The blood is assumed to contain copper (Cu) and silver (Ag) nanoparticles (NPs). The ciliary inner wall of the tube has been considered with small hair-like structures. The Phan-Thien-Tanner (PTT) fluid model is employed to describe the non-Newtonian rheological characteristics of blood. The conservative equations are normalized and simplified by utilizing scaling analysis with the assumption of low Reynolds number and large wavelength approximations. The analytical inspection exposes that the total entropy generation gets a decrement for mounting values of cilia length, while reversed impact is detected for an increment in heat source parameter. Hybrid nano-blood exhibits a greater total entropy number than mono nano-blood. This research study may be beneficial to medical experts and researchers in the field of embryology. Cysts in the ciliated fallopian tube, where embryos develop, are removed by using nanoparticles (nano-drug delivery).

熵产生和热源的意义:蠕动血流通过使用 Phan-Thien-Tanner 模型输送 Cu-Ag 纳米颗粒的纤毛管的情况

目前的推测性研究集中于分析在具有热源影响的管中悬浮混合纳米颗粒的纤毛诱导的血液蠕动中的熵产生和热传递现象。假设血液中含有铜 (Cu) 和银 (Ag) 纳米粒子 (NPs)。管的睫状内壁被认为具有小毛发状结构。Phan-Thien-Tanner (PTT) 流体模型用于描述血液的非牛顿流变特性。在低雷诺数和大波长近似的假设下,利用比例分析对保守方程进行归一化和简化。分析检查表明,总熵生成随着纤毛长度的安装值而减少,同时检测到热源参数增加的反向影响。混合纳米血液比单一纳米血液表现出更大的总熵数。这项研究可能对胚胎学领域的医学专家和研究人员有益。通过使用纳米颗粒(纳米药物递送)去除纤毛输卵管中的囊肿,其中胚胎发育。
