Numerical study of free surface flow based on smoothed particle hydrodynamics (SPH) method



The objective of this CFD research and Consultancy Project is to develop a meshfree CFD solver that adapts for the flows with free surface especially large deformation of a free surface. A parallel, multi-phase SPH code for numerical simulation of the flow field is developed.
An improved boundary treatment approach based on coupled boundary approach is proposed as part of our CFD Consulting Services so that the pressure of boundary particles is more accuracy and the simulation results of the flow field using the improved approach are better than that of the original approach. A non-reflection boundary treatment approach is proposed.
The SPH code is adopted to investigate the water entry of a solid body. The parallelized one-phase and two-phase SPH codes are adopted to simulate the whole process of a wedge entering water respectively. The comparison of the numerical results of the one-phase code and two-phase code is analyzed as part of the CFD Services scope of work.
Finally, the computational Fluid Analysis results of the two-phase code are verified by our experimental data. The different type of validation cases shows that the developed SPH code is quite robust and suitable for the simulation of the flow field with the interface or free surface.


Development of Shock-capturing technique for a discontinuous FEM method (HDG)


A novel shock-capturing technique for a discontinuous FEM method (HDG) is developed for an in-house code.
The strategy is developed for steady convection-diffusion problems and compressible Navier-Stokes equations of CFD Analysis Simulation. The HDG local problem is modified as part of our CFD Analysis Services to account for the discontinuous approximation inside these elements.
DG numerical fluxes are considered on the inter-sub-cells boundaries leading to a stabilized formulation, diminishing the oscillations in the vicinity of sharp fronts and shocks.
As a result, the CFD Simulation method can capture shocks within large high-order elements. Numerical examples, for convection-diffusion and compressible Navier-Stokes equations (laminar flow around NACA airfoil), show that the proposed method stabilizes the HDG solution in the presence of shocks and sharp fronts, with no additional degrees of freedom, preserving the compact stencil and computational efficiency of HDG methods.

Flow Around a Rectangle (used to learn OpenFOAM CFD Software) to access the effect of AR on wind circulation around the body. Several RANS models were used also in the Fluid Dynamic Analysis to see how circulation bubbles are predicted. Aerodynamics of a Rotating Wheel on the Ground.
The two approaches RANS and DES are used comparing them at the same computational time. Moreover, a high y+ value was used. This could be strange especially for DES usage. But the DES experiments the same lead to improvements towards experimental data, apart from an obvious more detailed wake pattern description.
