Hi,nThis is a very general question and therefore, I'm attempting to answer in very general terms.nPlease make sure your results are mesh independent.nPlease have sufficient inflation layers to resolve the boundary layers.nPlease make sure that your boundary conditions and material properties are consistent with the reference you are using.nPlease make sure that your simulation results are fully converged and that you obtain a steady state solution. nHere are some examples that might help you get started.nElectronics cooling using a heat sinknImpinging jet on a heated cylinder.nPlease feel free to make use of these free Ansys Innovation Courses (AIC) fluids courses to learn more about how to simulate fluid flow problems in Ansys Fluent. nI hope this helps.nThanks.nKarthikn
