Abstract: “Direct” small disturbance approaches to inviscid aerodynamic “inverse” or “design” problems in two and three-dimensional, subsonic, supersonic, and transonic flow, are given which extend the stream ...

Abstract: Steady, inviscid, planar and constant density shear flows past thin airfoils have strongly coupled thickness and camber flowfields which can be simply analyzed using some invariant properties of ...

Abstract: For flows with prescribed parallel shear far upstream, the vorticity generation term in the disturbance stream-function (Ψ) equation and the Bernoulli “constant,” both of which vary from stream ...

Abstract: The inverse problem, which determines an airfoil geometry given some specified surface pressure, is considered in the subsonic, thin-airfoil limit. The full governing equations are expanded in ...

Abstract: The fundamental geometrical characteristics of bevel gears have been discussed in this study. The mathematical modeling of the tooth surface geometry of bevel gears can be developed based on ...

Abstract: The “inverse” or “design” problem in aerodynamics, which solves for the airfoil shape that induces a prescribed chordwise surface pressure subject to additional requirements on trailing edge ...

Abstract: Architectural and structural considerations in the design of the 27‐story Wisma Dharmala office complex in Jakarta lead to the deployment of twincolumn clusters around the perimeter and interior of the tower block. Due to ...

Abstract: Two approaches for determination of the nonlinear planar modes of a cantilever beam are compared. In the first approach, the governing partial-differential system is discretized using the linear ...

Abstract: A complex-variable invariant-manifold approach is used to construct the normal modes of weakly nonlinear discrete systems with cubic geometric nonlinearities and either a one-to-one or a three-to-one ...
