... ABSTRACT To evaluate the availability of traditional turbulence stimulator in the towing tank test by using model ship at very low speed condition, we carried out a direct numerical simulation for boundary layer flow with a trapezoidal stud. The two Reynolds numbers were tested by changing...

... ABSTRACT Multi-Scale Flow Structures Can Be Observed In The Process Of Droplet Impact On A Deep Pool, Such As Central Jet, Splash, Micro-Droplets. We Have Performed 3-D Direct Numerical Simulation Of This Problem. By Using Block-Based Adaptive Mesh Refinement (Bamr) Algorithm, Highresolution...

... by vortex structures. Direct numerical simulations (DNS) are performed for this problem. Horizontal vortex tube and vortex ring are defined as two canonical problems for laminar free surface vortex connection problems. Particularly, the vortex structure free-surface evolution and surface secondary vorticity...

... nonlinear dispersive waves with slower variation in the transverse direction. In the two-dimensional case, the model predictions are compared with direct numerical simulations of the full equations and a good agreement is found. regime amplitude reservoir simulation guyenne solitary wave...

... equations are solved with direct numerical simulations based on the finite volume method (FVM) using the open source CFD (Computational Fluid Dynamics) code OpenFOAM. Deforming mesh technique is adopted to simulate the oscillation motion of the disk. The thickness ratio (thickness/diameter) of the disk...
