Numerical analysis of two dimensional steady flows over a triangular extended solid (thorn) attached to square cylinder positioned at front stagnation point and at rear stagnation point separately is reported at low Reynolds number (Re = 40). The variation of thorn length (l0 = 0.2,0.4 & 0.6) & inclination angle (H= 5, 10, 15 & 20) and its effect on the drag, pressure, shear stress, boundar…
