Covered from the vantage point of a user of a commercial flow package, Essentials of Computational Fluid Dynamics provides the information needed to competently operate a commercial flow solver. This book provides a physical description of fluid flow, outlines the strengths and weaknesses of computational fluid dynamics (CFD), presents the basics of the discretization of the equations, focuses on the understanding of how the flow physics interact with a typical finite-volume discretization, and highlights the approximate nature of CFD. It emphasizes how the physical concepts (mass conservation or momentum balance) are reflected in the CFD solutions while minimizing the required mathematical/numerical background. In addition, it uses cases studies in mechanical/aero and biomedical engineering, includes MATLAB and spreadsheet examples, codes and exercise questions. The book also provides practical demonstrations on core principles and key behaviors and incorporates a wide range of colorful examples of CFD simulations in various fields of engineering. In addition, this author: Introduces basic discretizations, the linear advection equation, and forward, backward and central differences Proposes a prototype discretization (first-order upwind) implemented in a spreadsheet/MATLAB example that highlights the diffusive character Looks at consistency, truncation error, and order of accuracy Analyzes the truncation error of the forward, backward, central differences using simple Taylor analysis Demonstrates how the of upwinding produces Artificial Viscosity (AV) and its importance for stability Explains how to select boundary conditions based on physical considerations Illustrates these concepts in a number of carefully discussed case studies Essentials of Computational Fluid Dynamics provides a solid introduction to the basic principles of practical CFD and serves as a resource for students in mechanical or aerospace engineering taking a first CFD course as well as practicing professionals needing a brief, accessible introduction to CFD.

Providing an ethnographic account of the Islamic Party of Malaysia (PAS) and its Youth Wing (Dewan Pemuda PAS), this book analyses the genesis and role of Islamic movements in terms of their engagement in mainstream politics. It explores the party's changing approach towards popular culture and critically investigates whether the narrative of a post-Islamist turn can be applied to the PAS Youth. The book shows that in contrast to the assumption that Islamic marketization and post-Islamism are reinforcing each other, the PAS Youth has strategically appropriated and integrated Islamic consumerism to pursue a decidedly Islamist - or 'pop-Islamist' - political agenda. The media-savvy PAS Youth elites, which are at the forefront of implementing new outreach strategies for the party, categorically oppose tendencies of political moderation among the senior party. Instead, they are most passionately calling for the establishment of a Syariah-based Islamic oder for state and society, although these renewed calls are increasingly expressed through modern channels such as Facebook, YouTube, rock music, celebrity advertising, branded commodities and other market-driven forms of social movement mobilization. A timely and significant contribution to the literature on Islam and politics in Malaysia and beyond, this book sheds new light on widespread assumptions or even hopes of "post-Islamism". It is of interest to students and scholars of Political Religion and Southeast Asian Politics.

Illusions of Democracy: Malaysian Politics and People offers an up-to-date and broad analysis of the contemporary state of Malaysian politics and society. Transcending disciplinary boundaries, it offers a look at Malaysian politics not only through the lens of political science but also anthropology, cultural studies, international relations, political economy and legal studies touching on both overlooked topics in Malaysian political life as well as the emerging trends which will shape Malaysia's future. Covering silat martial arts, Malaysia's constitutional identity, emergency legislation, the South China Sea dilemma, ISIS discourse, zakat payment, the fallout from the 1MDB scandal and Malaysia's green movement, Illusions of Democracy charts the complex and multi-faceted nature of political life in a semi-authoritarian state, breaking down the illusions which keep it functioning, to uncover the mechanisms which really underlie the paradoxical longevity of Malaysia's political, economic and social system.
