Available in PDF, EPUB and Kindle. Book excerpt: High fidelity nuclear reactor thermal hydraulic simulations are a hot research topic in the development of nuclear engineering technology. The three-dimensional Computational Fluid Dynamics (CFD) and Computational Multi-phase Fluid Dynamics (CMFD) methods have attracted significant attention in predicting single-phase and multi-phase flows under steady-state or transient scenarios in the field of nuclear reactor engineering. Compared with three-dimensional thermal hydraulic methods, the traditional one-dimensional system analysis method contains inherent defects in the required accuracy and spatial resolution for a number of important nuclear reactor thermal-hydraulic phenomena. At present the CFD method has been widely adopted in the nuclear industry, across both light water reactors and liquid metal cooled fast reactors, providing an effective solution for complex issues of thermal hydraulic analysis. However, the CFD method employs empirical models for turbulence simulation, heat transfer, multi-phase interaction and chemical reactions. Such models must be validated before they can be used with confidence in nuclear reactor applications. In addition, user practice guidelines play a critical role in achieving reliable results from CFD simulations.

Download or read book Numerical Simulation of Heavy Oil Droplets Mixing in Supercritical Water at Conditions Relevant to Supercritical Water Heavy Oil Upgrading written by Aniket Sanjay Patankar and published by . This book was released on 2020 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercritical water (SCW) crude oil upgrading is a promising technology for upgrading and desulfurization of heavy crude oil and residues. The outcome of this process is determined by an interplay of hydrocarbon cracking and condensation reactions, multicomponent phase equilibrium, phase separation and coke formation, and macroscale mixing governed by uid dynamics. These individual phenomena span several lengthscales and timescales, and are closely coupled, so that it is extremely difficult to uncover physical phenomena and estimate reaction rates by empirical means alone. Modeling studies of the SCW oil upgrading process are scarce, and pose the challenge of capturing the relevant physical phenomena in a tractable and computable framework. We include a review of SCW-oil upgrading research in the present study, and highlight these modeling challenges. In the present study, we introduce a modeling framework based on a Computational Fluid Dynamics (CFD) scheme developed in-house at the Reacting Gas Dynamics Lab at MIT, and specialized for partially miscible flows with non-ideal thermodynamics. Key features of our CFD scheme include the use of a sharp interface method with geometric advection, and a rigorous treatment of interfacial heat and mass transfer. Preliminary CFD results with a bench-scale reactor geometry are presented to highlight the computational cost of direct numerical simulations (DNS). The novel conditions of SCW oil upgrading result in large Reynolds numbers and very ne droplets at even at low ow velocities. Computational cost can be reduced significantly by developing submodels for estimating mixing rates of oil droplets in SCW. We present high-fidelity, droplet-scale mixing studies under quiescent and convective conditions. Two mixing timescales are quantified for the partially miscible system a droplet saturation timescale and a droplet dissolution timescale. Sherwood number is quantified and droplet deformation and internal circulation within the droplet are examined. Our results suggest that these ow phenomena could lead to significantly altered fractionation and phase separation behavior during convective mixing, as compared to the quiescent case. Equilibrium composition and surface tension vary rapidly with interfacial temperature in the system of interest. We nd that internal circulation within a droplet results in a more homogeneous interfacial temperature distribution. This permits the assumption of a unique equilibrium composition along the interface. However, the strong dependence of surface tension on interfacial temperature could lead to signicant Marangoni forces along the interface.

Download or read book Efficient High-Order Discretizations for Computational Fluid Dynamics written by Martin Kronbichler and published by Springer Nature. This book was released on 2021-01-04 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book introduces modern high-order methods for computational fluid dynamics. As compared to low order finite volumes predominant in today's production codes, higher order discretizations significantly reduce dispersion errors, the main source of error in long-time simulations of flow at higher Reynolds numbers. A major goal of this book is to teach the basics of the discontinuous Galerkin (DG) method in terms of its finite volume and finite element ingredients. It also discusses the computational efficiency of high-order methods versus state-of-the-art low order methods in the finite difference context, given that accuracy requirements in engineering are often not overly strict. The book mainly addresses researchers and doctoral students in engineering, applied mathematics, physics and high-performance computing with a strong interest in the interdisciplinary aspects of computational fluid dynamics. It is also well-suited for practicing computational engineers who would like to gain an overview of discontinuous Galerkin methods, modern algorithmic realizations, and high-performance implementations.

Available in PDF, EPUB and Kindle. Book excerpt: A numerical simulation is a computing calculation following a program that develops a mathematical model for a physical, social, economic, or biological system. Numerical simulations are required for analyzing and studying the behavior of systems whose mathematical models are very complex, as in the case of nonlinear systems. Capturing the resulting uncertainty of models based on uncertain parameters and constraints in confidence intervals (1-D), or more generally (>1-D) confidence regions, is very common for expressing to which degree the computed result is believed to be consistent with possible values of the targeted observable. This book examines the different methods used in numerical simulations, including adaptive and stochastic methods as well as finite element analysis research. This work is accompanied by studies of confidence regions, often utilized to express the credibility of such calculations and simulations.
