CFD analysis of SD 7003 airfoil at low reynolds number with a laminar kinetic energy based transition model

The characteristics of laminar separation bubbles (LSBs) on the SD 7003 airfoil have been extensively studied in the past at low Reynolds numbers. It has been found that the LSB is extensive, especially at airfoil at angle of attack (α) of 4º. To analyze separation, transition and reattachment of f...
