Available in PDF, EPUB and Kindle. Book excerpt: The compactness and high surface-to-volume ratios of microscale liquid flow devices make them attractive alternatives to conventional flow systems for heat transfer augumentation, chemical reactor or combustor miniaturization, aerospace technology implementations, as well as biomedical applications, such as drug delivery, DNA sequencing, and bio-MEMS, to name a few. While experimental evidence indicates that fluid flow in microchannels, especially in terms of wall friction and heat transfer performance, differs from macrochannel flow behavior, laboratory observations are often inconsistent and contradictory. Some researchers attributed the deviations to unknown microscale effects, which often turned out to originate from inappropriate approaches to analyze the new phenomena. Specifically, system parameters were neglected, which are not important on the macroscale but play important roles in microscale analyses The main objectives of the study are to identify important parameters for microscale liquid flows and nanoparticle suspensions, to find a physically sound way to analyze the new phenomena, and to provide mathematical models to simulate them. Scale analysis was found to be a valuable tool to determine which forces become important on the microscale. With increasing system miniaturization surface forces, such as surface tension and van der Waals forces, take over the control from body forces like gravity and pressure. Furthermore, surface roughness, viscous dissipation, and entrance region effects are very important liquid flow parameters in microscale conduits. In summary, for liquid flow in microchannels with a characteristic width or height of L e"10 [µm], the continuum approach, in conjunction with appropriate closure models, is appropriate to analyze microscale effects. Employing the porous medium layer (PML) idea, surface roughness effects on momentumand heat-transfer in micro-conduits were numerically investigated and verified with experimental.

Download or read book The computational model of nanofluid considering heat transfer and entropy generation across a curved and flat surface written by Sayer Obaid Alharbi and published by Infinite Study. This book was released on 2023-01-01 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The entropy generation analysis for the nanofluid flowing over a stretching/shrinking curved region is performed in the existence of the cross-diffusion effect. The surface is also subjected to second-order velocity slip under the effect of mixed convection. The Joule heating that contributes significantly to the heat transfer properties of nanofluid is incorporated along with the heat source/sink. Furthermore, the flow is assumed to be governed by an exterior magnetic field that aids in gaining control over the flow speed. With these frameworks, the mathematical model that describes the flow with such characteristics and assumptions is framed using partial differential equations (PDEs). The bvp4c solver is used to numerically solve the system of non-linear ordinary differential equations (ODEs) that are created from these equations. The solutions of obtained through this technique are verified with the available articles and the comparison is tabulated. Meanwhile, the interpretation of the results of this study is delivered through graphs. The findings showed that the Bejan number was decreased by increasing Brinkman number values whereas it enhanced the entropy generation. Also, as the curvature parameter goes higher, the speed of the nanofluid flow diminishes. Furthermore, the increase in the Soret and Dufour effects have enhanced the thermal conduction and the mass transfer of the nanofluid.

Download or read book Modeling and Simulation of Nanofluid Flow Problems written by Snehashish Chakraverty and published by Springer Nature. This book was released on 2022-05-31 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: In general, nanofluid is suspension of nanometer-sized particle in base fluids such as water, oil, ethylene glycol mixture etc. Nanofluid has more thermal conductivity compared to the base fluids. As such, the nanofluid has more heat transfer capacity than the base fluids. In order to study nanofluid flow problems, we need to solve related nonlinear differential equations analytically or numerically. But in most cases, we may not get an analytical solution. Accordingly, the related nonlinear differential equations need to be solved by efficient numerical methods. Accordingly, this book addresses various challenging problems related to nanofluid flow. In this regard, different efficient numerical methods such as homotopy perturbation method, Galerkin's method, and least square method are included. Further, the above practical problems are validated in special cases. We believe that this book will be very beneficial for readers who want firsthand knowledge on how to solve nanofluid flow problems.

This book was released on 2022-06-02 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micro and Nanofluid Convection with Magnetic Field Effects for Heat and Mass Transfer Applications using MATLAB® examines the performance of micro and nanofluids with various physical effects such as magnetic field, slip effects, radiation and heat sources. Heat and mass transfer enhancement techniques are widely used in many applications in the heating and cooling or freezing process to make possible a reduction in weight and size or enhance performance during heat and mass exchanges. The book covers the two categories of flow techniques, active and passive. It discusses various considerations in the engineering sciences in the melting process, polymer industry and in metallurgy. To be more precise, it may be pointed out that many metal surgical developments involve the cooling of continuous strips or filaments by drawing them through a quiescent fluid, and in that process of drawing, these strips are sometimes stretched. In all these cases, the properties of the final product depend, to a great extent, on the rate of cooling by drawing such strips in an electrically conducting fluid subject to a magnetic field and thermal radiation. Provides information about the governing equations for all three types of flow geometries Explains micro polar fluid flow modeling Offers detailed coverage of boundary value problems using MATLAB®
