Hello,nI agree that the simulation examples covered in this course, with the exception of 'Blood Flow through the Circle of Willis' (link below), use the turbulence models. The reason for including these examples is most flows in engineering applications are turbulent in nature. Very flow applications involve a laminar flow.nAlso, if you go through the individual lessons on external and internal flows in this course, we cover various viscous laminar concepts involving:nCreeping flow past a sphere - Stoke's solutionnOseen's correction to Low Re laminar flownCouette flow between flat plates and rotating concentric cylinders, and nPoiseuille flow (incl. Hagen-Poiseuille flows)nIn addition to highlighting some laminar flow applications, we also wanted to give a flavor for some important engineering applications in our course. Because of all these reasons, the name of this course is - Viscous Laminar Flows.nMoreover, in the Learning Track - 'Basics of Fluid Dynamics', we cover quite a few simulation examples involving laminar flows. To name a few: nFalling Sphere Viscometer (What are Fluids?):nPitot Tube (Course - Simple Approximations of Fluid Flows):nI hope this addresses your question.nBest Regards,nKarthikn
