ABSTRACTThis study is a fundamental study in the development of a renewable flow control method and is very promising. The main objective of this study was to obtain characterization of the use of a plasma actuator on a boundary layer flow that is able to manipulate this area by studying the interactions that exist in the boundary layer.This research was done by using two approaches, experimental approaches and computational. On the approach to the measurement experimental its downstream region at a distance of 15 mm and 30 mm from the center of the plasma by varying frequencies ranging from 6 kHz up to 10 kHzFrom the experimental results obtained velocity profile, displacement thickness, momentum thickness, thickness of energy with the best frequency variance at 6 kHz with displacement thickness, thickness momentum, energy thickness of each is 2,343 mm, 0.94 mm and 0.152 mm. Then the experimental results were compared with computational to get the same tendency in the downstream region"

"This is the first book published in English devoted solely to the boundary function method, which is one of the asymptotic methods. This method provides an effective and simple way to obtain asymptotic approximations for the solutions of certain ordinary and partial differential equations containing small parameters in front of the highest derivatives. These equations, called singularly perturbed equations, are often used in modeling. In addition to numerous examples, the book includes discussions on singularly perturbed problems from chemical kinetics and heat conduction, semiconductor device modeling, and mathematical biology. The book also contains a variety of original ideas and explicit calculations previously available only in journal literature, as well as many concrete applied problems illustrating the boundary function method algorithms. Quite general asymptotic results described in the book are rigorous in the sense that, along with the asymptotic algorithms, in most cases the theorems on estimation of the remainder terms are presented. A survey of results of Russian mathematicians on the subject is provided; many of these results are not well known in the West."

"This book presents a new approach to analyzing initial-boundary value problems for integrable partial differential equations (PDEs) in two dimensions, a method that the author first introduced in 1997 and which is based on ideas of the inverse scattering transform. This method is unique in also yielding novel integral representations for the explicit solution of linear boundary value problems, which include such classical problems as the heat equation on a finite interval and the Helmholtz equation in the interior of an equilateral triangle."

"This self-contained book addresses the three most popular computational methods in CAE (finite elements, boundary elements, collocation methods) in a unified way, bridging the gap between CAD and CAE.It includes applications to a broad spectrum of engineering (benchmark) application problems, such as elasto-statics/dynamics and potential problems (thermal, acoustics, electrostatics). It also provides a large number of test cases, with full documentation of original sources, making it a valuable resource for any student or researcher in FEA-related areas."
