A numerical automation procedure has been developed to be used in conjunc- tion with an inverse hodograph method for the design of controlled diffusion blades. With this procedure a cascade of airfoils with a prescribed solidity, inlet Mach number, inlet air flow angle and air flow turning can be produced automatically. This paper deals with the Design and Analysis of a Controlled Diffusion Aerofoil (CDA) Blade Section for an Axial Compressor Stator and Effect of incidence angle and Mach No. on Performance of CDA. From the reviews: “The book treats a large class of fully nonlinear parabolic PDEs via probabilistic methods. The monograph may be strongly recommended as an excellent reading to PhD students, postdocs et al working in the area of controlled stochastic processes and/or nonlinear partial differential equations of the second order. recommended to a wider audience of all students Brand: Springer-Verlag Berlin Heidelberg. Using the modelling capability of Siemens NX PLM software and its knowledge-based design automation, the solid model of axial pump impeller's blade can be generated. The automated modelling.
A method is presented for automating compressor blade design using numerical optimization and is applied to the design of a controlled diffusion stator blade row. A general purpose optimization procedure is employed, which is based on conjugate directions for locally unconstrained problems and on feasible directions for locally constrained. The main advantage of the inverse design methods is the ability to design in detail very specific blade geometries, such as controlled diffusion blades and shock‐free transonic blades. A design tool for generating 3D blades for various turbomachinery applications using a parametric approach has been developed. The tool can create a variety of 3D blade geometries based on only a. Modern blades are aerodynamically optimised for every individual section and ‘controlled diffusion airfoils’ (CDA) have been developed as a standard. This kind of blading individually controls the development of the aerodynamic boundary layer along the profile and can be used to optimise the individual sections according to given.
Dutta et al.  describes an automated process of a non-dimensional quasi-3D blade design with parameterization of the camber-line angle and thickness distributions and blade inlet and outlet.

Introduction. Diffusion is the most important mechanism used to control drug release from pharmaceutical previously described, the resulting release kinetics essentially depend on the size and shape of the dosage d release profiles can be achieved by adjusting the geometry and the dimensions of the system.
