In the present study the usefullness of a large eddy simulation for transition is examined. Numerical
results of such simulations are presented from a study to determine the characteristics of a flow induced by a thermal line source. The first bifurcation to time dependent motion and the route to chaos are considered. Qualitatively these features are in good agreement with theory. The governing equations, the concept of large eddy simulation and the numerical code that was used are described extensively. Also the results from a literature survey are presented. Special attention is paid to analytical solutions for the boundary layer equations for laminar flow and the stability of these solutions. It includes also overall conservation principles for turbulent plumes and results obtained by experiments.
