Numerical simulation of laminar turbulent transition in a rectangular duct flow is made using a spectral method. Aspect ratio of the duct is fixed to unity, in which case the flow has been known to be stable from the linear stability calculation and this is in contrary with the experimental observation. It is obtained from the simulation that two-dimensional secondary flow occurs when Reynolds number of the flow is 2750, and three dimensional turbulent flows occur when the Reynolds numbers are greater than 3000.
