Numerical studies of laminar-to-turbulent transition in a separation bubble subjected to two free-stream turbulence levels (FST) have been performed using Large-Eddy Simulation (LES). Separation of the laminar boundary layer occurs at a curvature change over a plate with a semi-circular leading edge at Re = 3450 based on the plate thickness and the uniform(More)
This paper improves the Smith-Waterman algorithm. On the one hand, it present the two-character alignment, improve the scoring function and scoring matrix to enhance the specificity and reduce the randomness of the matching sequences. On the other hand, changing the score matrix overall storage to two-line storage drastically reduces the complexity of the(More)
Transition from laminar flow to turbulent flow occurs very often and plays a crucial role in many practical engineering flows. There are many different kinds of transition and broadly speaking they can be classified into three categories: classical transition in attached boundary; bypass transition in attached boundary layer and separated boundary layer(More)
