WebFullscreen. A simple way of modelling the cross section of an airfoil (or aerofoil) is to transform a circle in the Argand diagram using the Joukowski mapping, . The map is conformal except at the points , where the complex derivative is zero. You can drag the circle's center to give a variety of airfoil shapes, but it should pass through one ... http://oilproduction.net/files/04-ENGINEERING_DESIGN_GUIDELINES_fluid_flow_hydraulic_surge_rev_web.pdf owlbehome.com

The joukowsky equation

Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid in motion, usually a liquid but sometimes also a gas is forced to stop or change direction suddenly; a momentum change. This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe.
