... (TKE), quadrant analysis, and Q-criteria for vortices, which are responsible for the development of various problems such as scour-hole around the cylindrical pier arrangements, disturbance around industrial and marine structures. The spectral analysis was performed to examine the energy distributions...

... using bubbles with those using solid particles. Bubbles showed good trace ability in the region of 15 < Re S < 75 ; however, some discrepancies showed at high velocity gradient region of Re S ≈ 1000 . The fitted vorticity reduction rate would give reference for the prediction in a real flow when...

... -directional magnetic field is more effective in reducing the convection intensity. As the inclination angle increases, multicellular flows begin to develop on both sides of the enclosure for higher values of the Hartmann number if the enclosure is under the x -directional magnetic field. The vorticity...
