Aiming at the problem of transition in fluid dynamics

a empirical correlation based B-C transition model is proposed. This transition model does not change the number of transport equations

and overcomes the disadvantage that the transition model containing the transport equation will change the number of equations in the calculation process. B-C transition model uses an intermittency function to multiply the production term of the SA turbulence model to implement the transition simulation. The transition model was calibrated by the experimental data of the zero pressure gradient flat plate. Based on the calibrated transition model

the flow over the twodimensional low speed airfoil was investigated. Comparison between the calculated results and the experiment data indicates that the B-C transition model after calibration can more accurately simulate the transition location of the flat plate case; in the moderately high and low Reynolds number range

the B-C transition model can calculate the aerodynamic coefficients more accurately at moderately high angle of attack.
