![]() It’s nothing exciting but a result I knew I could verify from having done these calculations manually and from other technical references (first rule of simulation, trust but verify!).įigure 1 shows a simple solid model of a hollow cylinder to represent our pipe. ![]() It is a 100-ft horizontal length of 4-in-diameter pipe. ![]() This is a model I used when I was evaluating various CFD packages. We will start with a simple model of water flow in a pipe. So I write this article using the approach and models that introduced me to CFD and the eventual selection of SOLIDWORKS Flow Simulation as my CFD package. However, as I more recently evaluated CFD software and its integration graphical interfaces, I came to realize its power not only in flow, but also in thermal analysis, which was my main area of interest at the time. Initially, I did not see many practical industrial applications for CFD and stuck with custom code, rules of thumb and spreadsheets to get the job done. I had been a finite element user for many years before entering the world of flow simulation/computational fluid dynamics (CFD).
