... ordinary differential equations, which are solved numerically using MATLAB . The analysis reveals dual solutions within certain parameter ranges, accompanied by a saddle-node bifurcation and flow separation, indicating critical transitions in flow structure. A comprehensive temporal stability analysis...

... transformations and are solved using the bvp4c routine that implements the three-stage Lobatto-IIIa formula. Stability analysis has been performed to examine the consistent solution. Findings The study observes that multiple solutions arise only in opposing buoyancy cases. Notably, flow separation is delayed...

... that for the selected velocity ratios, the method is able to improve the shock-upstream boundary layer and counteract flow separation, significantly increasing the airfoil aerodynamic performance. Originality/value The moving wall concept as a means of normal shock wave–turbulent boundary layer interaction...

... improve the existing negative Spalart-Allmaras turbulence model with respect to shock-induced flow separation. Originality/value A comprehensive workflow is demonstrated that yields insights on which input features and which ML model should be used in the context of the FIML approach (3) j...

... By optimizing the three influencing factors, diameter, streamwise length and streamwise position, the optimized ETD has achieved a maximum drag reduction of 7.04%. The analysis of flow field results shows that enhancing turbulence can effectively suppress flow separation and reduce the negative pressure...

...Le Dian Zheng; Yi Yang; Guang Lin Qiang; Zhengqi Gu Purpose This paper aims to propose a precise turbulence model for automobile aerodynamics simulation, which can predict flow separation and reattachment phenomena more accurately. Design/methodology/approach As the results of wake flow...

..., the implementation of RVGs on aerofoil has proven to decrease the flow separation and enhance the aerodynamic performance of aerofoils. The effect on flow structure and aerodynamic performance has shown to be dependent on dimensions, chordwise location and spanwise distribution of rods. The implementation of devices...
