The Design and Analysis of a Micro Squeeze Flow Rheometer
… describes the analysis and design of a micro squeeze flow rheometer. The need to analyse the rheology of complex liquids occurs regularly in industry and during research. However, frequently the amount of fluid available is too small, precluding the use of conventional rheometers. Conventional …

Using Non-Lubricated Squeeze Flow to Obtain Empirical Parameters for Modeling the Injection Molding of Long-Fiber Composites
… polypropylene during two homogeneous flows (startup of shear and planar extension) was compared. This comparison had not been performed in the literature previously, and revealed that fiber orientation is significantly faster during planar extension. This contradicts a long-held …

Modeling Fiber Orientation using Empirical Parameters Obtained from Non-Lubricated Squeeze Flow for Injection Molded Long Carbon Fiber Reinforced Nylon 6,6
… orientation. The properties and behavior of the flow of a fiber reinforced polymer composite during molding are directly related to the mechanical properties of the completed part. Flow affects the orientation of the fibers within the polymer matrix and at locations within the mold cavity. The …

Resin percolation and intimate contact in fast processing of thermoplastic composites
… imaging and scaling analysis that percolation flow, rather than squeeze flow, of resin through fibers is the dominant mechanism to achieve intimate contact in rapid TPC processes such as automated fiber placement (AFP) and welding. A 1D intimate contact model based on resin percolation, derived …

Filler effects in resole adhesive formulations
… lubrication approximation for the viscous force, squeeze flow of adhesives between two flat, impermeable steels and between steel and porous wood can be successfully modeled. However, deviations from theory were encountered as related to the method of adhesive application. Both meniscus force in …

Influência da adição do resíduo proveniente do corte de mármore e granito (RCMG) nas propriedades de argamassas de cimento Portland
… dos ensaios de abatimento de tronco de cone (flow table), squeeze-flow e reometria. No estado endurecido, foram realizados ensaios para a determinação das propriedades mecânicas (resistência à tração na flexão, à compressão axial e à tração por compressão diametral) e físicas (absorção de água …

Theoretical and Experimental Atomic Force Microscopy Investigations of Staphylococcus aureus
… fluids by considering them as fluids undergoing squeeze flow. The four spring model was validated theoretically with a more complex, two-dimensional Newtonian and viscoelastic (Phan-Thien Tanner) finite element model. The models were capable of predicting force curves, and experimental force …

Modeling of Microstructures and Stiffness of Injection Molded Long Glass Fiber Reinforced Thermoplastics
… is determined locally by the corresponding local flow-type and used in fiber orientation simulation. The application of the variable strain reduction factor in fiber orientation simulations for both non-lubricated squeeze flow and injection molded center-gated disk, allows the simulated fiber …

Direct numerical simulation of viscoplastic particulate flows
… to modelling suspensions in viscoplastic fluid flows. Firstly, for fully resolved particle suspensions---regardless of the carrier fluid---the discretisation scheme must cope with disparate length scales at the particle boundaries and wider flow field. In this work we adopt the overset grid …

Rheological Properties of Peanut Paste and Characterization of Fat Bloom Formation in Peanut-Chocolate Confectionery
… of medium oleic paste. The absolute value of the flow index behavior was 1 for the high oleic peanut paste, suggesting friction in the experimental apparatus, even with use of Teflon plates. The peanut chocolate candies took around 45 days for significant dulling of the chocolates with temperature …

Design and Development of a Squeeze-Mode Rheometer for Evaluating Magneto-Rheological Fluids
… (MR) fluids operated in the non-conventional squeeze mode through the use of a custom designed rheometer. Squeeze mode is the least understood of the three operational modes of MR fluid and thus its potential has yet to be realized in practical applications. By identifying the behavior of MR …

Characterization of Carbon Mat Thermoplastic Composites: Flow and Mechanical Properties
… agreement with the experimental results. Flow tests simulating the compression molding process were conducted on the CMT to determine what factors affect the flow viscosity of the CMT. The melt viscosity of the neat PP was measured using cone and plate rheometry at temperatures between …

Rheology of cement-based materials used for large-scale 3D printing
L'impression 3D béton introduit une toute nouvelle technique de production d'éléments en béton. Les avantages de cette technique par rapport à la méthode de construction conventionnelle basée sur l’utilisation de coffrage sont (1) une production plus facile et moins coûteuse des éléments à …
