Mathematical modeling and computer simulation are useful tools for improving materials processing. While courses in materials processing have covered modeling, they have traditionally been devoted to one particular class of materials, that is, polymers, metals, or ceramics. This text offers a different approach, presenting an integrated treatment of metallic and non-metallic materials. The authors show that a common base of knowledge - specifically, the fundamentals of heat transfer and fluid mechanics - provides a unifying theme for these seemingly disparate areas. Emphasis is placed on understanding basic physical phenomena and knowing how to include them in a model. The book also treats selected numerical methods, showing the relationship between the physical system, analytical solution, and the numerical scheme. A wealth of practical, realistic examples are provided, as well as homework exercises. Students, and practising engineers who must deal with a wide variety of materials and processing problems, will benefit from the unified treatment presented in this book.
Had General George Washington lived anywhere other than Mount Vernon, Virginia, Washington, D.C., might not exist. In this exciting collection of hidden tales from Northern Virginia, author Charles Mills highlights the important role that this region played in our nation's history from colonial to modern times. Read about the Rebel blockade of the Potomac River, the imprisonment of German POWs at super-secret Fort Hunt during World War II and the building of the Pentagon on the same site and in the same configuration as Civil War, era Fort Runyon. Meet Annandale's "bunny man, "? who inspired one of the country's wildest and scariest urban legends; learn about the slaves in Alexandria's notorious slave pens; and witness suffragists being dragged from the White House lawn and imprisoned in the Occoquan workhouse. Mills masterfully relates these and other colorful tales of the people and events that left their imprints on Northern Virginia and the nation.
