Exact solutions of the linear water-wave problem describing oblique waves over a submerged horizontal cylinder small (but otherwise fairly arbitrary) cross-section in two-layer fluid are constructed form convergent series powers parameter characterizing “thinness” cylinder. The terms these expressed through solution exterior Neumann for Laplace equation flow unbounded past obtained describe tra...

Breaking waves interaction with two tandem cylinders are numerically studied using Computational Fluid Dynamic (CFD) software OpenFOAM. The effects of transverse inclined angles the downstream cylinder and separation distances between on breaking wave loads free surface elevations investigated. interface air water phases is captured by Volume (VOF) method. Shear Stress Transport k−ω(SSTk−ω) tur...

A systematic study of the effects of cell geometry on the dynamics of large-scale flows in turbulent thermal convection is carried out in horizontal cylindrical cells of different lengths filled with water. Four different flow modes are identified with increasing aspect ratio Γ . For small aspect ratios (Γ 6 0.16), the flow is highly confined in a thin disc-like cell with a quasi-two-dimensiona...
