We briefly discuss the fundamental aspects of polymer blends, including experimental observations, theories, and a variety of molecular simulations and models for mixtures of two or more polymeric materials. In particular, this study deals with the description of coarse-grained techniques that can offer perspectives into the collective behavior and properties of complicated systems. Additionally, a detailed analysis of their structural, rheological, and mechanical properties via computation is also examined. Lastly, we summarize important findings and highlight points to be carefully considered in modeling polymer blends system accompanied by an outlook on the extension of current studies to complicated systems of many blending types.</p></div>","PeriodicalId":683,"journal":{"name":"Korea-Australia Rheology Journal","volume":"35 4","pages":"249 - 266"},"PeriodicalIF":1.3,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13367-023-00076-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135667314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To measure blood damage in a DLC, the Eulerian approach is generally used without contemplating exposure time or history of blood exposure to shear stresses. Alternatively, Lagrangian approach has also been recently employed for a Newtonian blood flow through a DLC, thereby leaving a research gap on the impact of variable shear rate in case of non-Newtonian blood flow. In the present study, the hemodynamic performance of DLC is investigated using different non-Newtonian models by applying Lagrangian approach. Moreover, the motion of RBC was tracked inside the cannula to predict its behavior during the motion. The results showed that the return lumen had higher pressure, velocity, and shear stress values than other parts of the DLC. In addition, recirculation was observed due to the mixing of blood coming from different inlets and found increase with increasing flow rate of blood. Moreover, it was found that the blood damage increased with increasing flow rate. There was more blood damage in the Newtonian model than in the other non-Newtonian models at higher flow rates. However, the Carreau model showed more blood damage at lower flow rates than the other models. The Cross model showed DLC’s higher efficacy in delivering oxygenated blood to the tricuspid outlet because it showed the least blood damage among all other models. It was also concluded that the efficacy of the DLC to deliver oxygenated blood to the tricuspid outlet decreases with increasing blood flow rate.</p></div>","PeriodicalId":683,"journal":{"name":"Korea-Australia Rheology Journal","volume":"35 4","pages":"373 - 389"},"PeriodicalIF":1.3,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135643933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To estimate the effect of the aspect ratio on the rheological and electrical percolation behavior, the linear rheological properties of suspensions and the electrical properties of the resulting films are systematically assessed. The microstructure of the suspensions and the surface morphology of the films are visualized using optical microscope (OM) and field emission scanning electron microscope (FE-SEM), respectively. Observations from OM analyses reveal that suspensions containing higher aspect ratio AgNW (Ag1000) exhibit larger flocculated clusters, resulting from the entanglement of the nanowires. As results, PVA/Ag1000 suspensions show higher linear viscoelasticity (as indicated by <i>G′</i> and <i>G″</i>) when compared to PVA/Ag714 suspensions. However, unlike linear viscoelasticity, the electrical conductivities of PVA/Ag1000 films are lower than those of PVA/Ag714 films. This observation is attributed to the alignment of AgNWs during coating process providing substantial deformation and rapid alignment. Furthermore, SEM images of the films confirm the importance of retaining the flocculated clusters to achieve the desired electrical properties.</p></div>","PeriodicalId":683,"journal":{"name":"Korea-Australia Rheology Journal","volume":"36 1","pages":"15 - 24"},"PeriodicalIF":2.2,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135791076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These mixers utilize chaotic advection as their mixing mechanism in the laminar flow regime. The review first focuses on the flow and mixing characteristics of these mixers, considering the influence of the operating conditions and design variables. The advantages and flexibility of the BPPM and GPPM over the original PPM are highlighted. The investigation covers mixing performance in both the creeping and non-creeping flow regimes. In addition, this review examines the impact of thixotropy and fluid inertia on mixing performance of the mixers, revealing irregular trends. It emphasizes the importance of carefully considering thixotropy and inertia when selecting appropriate mixing protocols and operating conditions. Furthermore, the potential use of chaotic mixing by the BPPM in filtration processes is briefly reviewed. In conclusion, the review summarizes the limitations of the previous studies and suggesting future research directions. Further studies are expected to explore the potential of these types of mixers in improving mixing performance in various industries, particularly those dealing with rheologically complex fluids.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":683,"journal":{"name":"Korea-Australia Rheology Journal","volume":"35 4","pages":"229 - 247"},"PeriodicalIF":1.3,"publicationDate":"2023-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135305612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One, therefore, derives N1S and N1E related to Weissenberg’s number and Trouton’s ratio. The classic White–Metzner viscoelastic constitutive equation coupled with the recent GNF-X (Generalized Newtonian Fluid eXtended) weighted shear/extension viscosity has the potential to show the typical vortex growth in entry flow simulations. Based on the improved White–Metzner model, demonstrating the opposite effect of N1S and N1E with respect to strain rates is evident. N1S mainly dominates the shell layer near the wall boundary at high strain rates, whereas N1E controls the center core at low strain rates. In contraction flow simulations, the predicted slit-die velocity profile is in good agreement with experimental data. It is significant to conclude that N1E hinders flow and N1S facilitates flow. In addition, a comparison of extensional-thickening and extensional-thinning viscosity curves for the velocity profile is discussed herein.</p></div>","PeriodicalId":683,"journal":{"name":"Korea-Australia Rheology Journal","volume":"35 4","pages":"307 - 321"},"PeriodicalIF":1.3,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135826816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
