Book excerpt: This work couples the two enabling technologies of wake-integral drag prediction and Vorticity Confinement (VC) for the improved prediction of drag from an Euler CFD simulation. Induced drag computations of a thin wing are shown to be more accurate than the more common method of surface pressure integration when compared to Prandtl lifting-line theory. Furthermore, the Vorticity Confinement method is shown to improve trailing vortex preservation and counteract the shift from induced to entropy drag as the distance with which the vortex convects downstream of the wing increases. The desired application of this work is drag prediction, most notably induced drag, for aerodynamic design. High-fidelity Euler CFD simulations are desirable as they provide the most complete inviscid flowfield solution. However, accurate induced drag prediction via the surface integration of pressure is generally intractable barring a sufficiently refined surface grid and resultant increase in computational load. Furthermore, the alternative wake-integral technique for drag prediction suffers from numerical dissipation. VC is shown to control the numerical dissipation with very modest computational overhead. VC is implemented in both a two-dimensional finite-volume Euler code written by the author as well as the commercial cfd code ANSYS FLUENT. The two-dimensional research code is used to test specific formulations of the VC body force terms and illustrate the computational efficiency of the method compared to a 'brute force' reduction in spatial step size. For a three-dimensional wing simulation, AN-SYS FLUENT is employed with the VC body force terms added to the solver with user-defined functions (UDFs).

Available in PDF, EPUB and Kindle. Book excerpt: New Edition Now Covers Shock-Wave Analysis An in-depth presentation of analytical methods and physical foundations, Analytical Fluid Dynamics, Third Edition breaks down the "how" and "why" of fluid dynamics. While continuing to cover the most fundamental topics in fluid mechanics, this latest work emphasizes advanced analytical approaches to aid in the analytical process and corresponding physical interpretation. It also addresses the need for a more flexible mathematical language (utilizing vector and tensor analysis and transformation theory) to cover the growing complexity of fluid dynamics. Revised and updated, the text centers on shock-wave structure, shock-wave derivatives, and shock-produced vorticity; supersonic diffusers; thrust and lift from an asymmetric nozzle; and outlines operator methods and laminar boundary-layer theory. In addition, the discussion introduces pertinent assumptions, reasons for studying a particular topic, background discussion, illustrative examples, and numerous end-of-chapter problems. Utilizing a wide variety of topics on inviscid and viscous fluid dynamics, the author covers material that includes: Viscous dissipation The second law of thermodynamics Calorically imperfect gas flows Aerodynamic sweep Shock-wave interference Unsteady one-dimensional flow Internal ballistics Force and momentum balance The Substitution Principle Rarefaction shock waves A comprehensive treatment of flow property derivatives just downstream of an unsteady three-dimensional shock Shock-generated vorticity Triple points An extended version of the Navier‒Stokes equations Shock-free supersonic diffusers Lift and thrust from an asymmetric nozzle Analytical Fluid Dynamics, Third Edition outlines the basics of analytical fluid mechanics while emphasizing analytical approaches to fluid dynamics. Covering the material in-depth, this book provides an authoritative interpretation of formulations and procedures in analytical fluid dynamics, and offers analytical solutions to fluid dynamic problems.
