of Mathematics, St. Thomas College, Kozhencherry ABSTRACT Conformal mapping method is a promising problem solver in the areas of physics, Engineering and Aerodynamics due to its increasing speed of digital computation and decreasing cost. Aerodynamics is the branch of fluid mechanics that deals with the determination of the fluid mechanical forces and moments on bodies of interest. Due to the complexity of the ow around it, a lot of simpli cations must be done. Conformal transformations, or mappings, have many important properties and uses.

One property relevant to image transformation is the preservation of local shape (except sometimes at isolated points). Some results of this investigation are presented in this Technical Memorandum, which is essentially a compendium of shapes (aerodynamic and non-aerodynamic) in the z-plane obtainable by conformal mappings from the unit circle in a C-plane.

In this paper, we use the conformal mapping technique to model the uid ow around the NACA 0012, 2215, and 4412 airfoils by using the Joukowsky transformation to link the Aerodynamic in air foil • Now we will use a conformal mapping technique to study flow of fluid around a airfoil. We assume the reader is familiar with the basics of complex numbers and complex arith-
This di culty is based on uid interactions around aircraft and generally on the aspect that one wants a solution of the practical part of aerodynamics.

This example uses a 2-D conformal transformation to warp an image. Conformal mapping have been used in studying the air ow around an airplane. conformal mapping and the joukowski transformation Posted by admin in AERODYNAMICS on February 14, 2016 The method of solution for our model airfoil problem is to map the airfoil (which is in the physical plane Y = x + iz) to a circular cylinder in the / = g + ih plane through the conformal mapping Y …
Conformal mappings can be effectively used for constructing solutions to the Laplace equation on complicated planar domains that are used in fluid mechanics, aerodynamics, thermomechanics, electrostatics, elasticity, and elsewhere.
