 February 4, 2006, 06:07 Pressure coefficient #1 Giuseppe Guest   Posts: n/a Hello to all, I have studied, with Fluent, the problem of flow past a circular cylinder in a uniform stream and I have plotted in XY graphics the pressure coefficient vs position(m). I have obtained two curves, one for the upper surface and one another for the lower surface! The questions are: 1) The direction of the pressure coefficient is orthogonal to the cylinder surface? 2) How can I plot the pressure coefficient distribution only for the upper surface and only for the lower surface, in two separate graphics? 3) How can I plot, in Fluent, the pressure coefficient vs angle? Thanks a lot

I'm using Excel to transform from Cartesian to cylindrical coordinates... jzc likes this.
