Book Description
A procedure for calculating 3-D, compressible laminar boundary layer flow on general fuselage shapes is described. The boundary layer solutions can be obtained in either nonorthogonal 'body oriented' coordinates or orthogonal streamline coordinates. The numerical procedure is 'second order' accurate, efficient and independent of the cross flow velocity direction. Numerical results are presented for several test cases, including a sharp cone, an ellipsoid of revolution, and a general aircraft fuselage at angle of attack. Comparisons are made between numerical results obtained using nonorthogonal curvilinear 'body oriented' coordinates and streamline coordinates. Wie, Yong-Sun Unspecified Center BOUNDARY LAYER FLOW; COMPRESSIBLE BOUNDARY LAYER; COMPUTATIONAL FLUID DYNAMICS; FUSELAGES; LAMINAR BOUNDARY LAYER; THREE DIMENSIONAL BOUNDARY LAYER; ANGLE OF ATTACK; COMPUTER PROGRAMS; CONES; COORDINATES; CROSS FLOW; ELLIPSOIDS...

Book Description
Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
