HI
I want to simulate vortex shedding downstream 2D circular cylinder with 200 Reynolds number, my mesh is correct. i want to know the best turbulence model to get accurate and better results, i have simulated first using laminar model and got VS I am asked to do this using some turbulent model k-epsilon k-omega or any one else suggest me please with reason Thanks in advance

thank you , can i do my research work on the basis of laminar model for a publication second is someone told me that laminar model is ideal model , and if i want to simaulate transient flow in fluent i have to use any other model , is it right? thanks

he(a senior student) told me laminar model is not suitable , ideal doesnt means best for my case , ideal in sanse like carnot cycle which is ideal but do not exist, means i can not present results based on laminar model ..

Your friend is wrong. Laminar flow is quite real and at a Re=200 the flow around a cylinder is laminar, even in the real world.

I did it again recently. Do you need all files? See this thread, you will very useful info here http://www.cfd-online.com/Forums/ans...cylinders.html
