?Time Dependent CFD Simulation: Vortex Shedding? What is Vortex shedding in the first place? Vortex shedding is a phenomenon?when the wind blows across a structural member, vortices are shed alternately from one side to the other, and where alternating low-pressure zones are generated on the downwind side of the structure, giving rise to a fluctuating force. This phenomenon is of major importance in engineering design because the alternate formation and shedding of vortices also create alternating forces, which occur more frequently as the velocity of the flow increases.

?? Let's revisit one of our enlightening blog posts! Reynolds Number The Reynolds number stands as a cornerstone for fluid dynamicists and CFD engineers, serving as one of the most significant dimensionless numbers. It encapsulates the ratio between inertia force and viscous force acting upon fluid elements. In our blog, we delve into the foundational principles of the Reynolds number and its extensive utility in CFD simulations. From mesh preparation to determining the initial cell thickness via y+, calculating turbulence intensity, establishing boundary conditions for heat transfer coefficients, computing friction coefficients, scaling, and ultimately post-processing and analyzing CFD results, the Reynolds number plays a pivotal role at every step. Undoubtedly, the Reynolds number emerges as the paramount non-dimensional parameter for CFD engineers and fluid dynamicists alike.

Today I’m excited to share the results of the project developed for the exam of Simulation and modelling of turbulent flows held by professor Andrea Cimarelli. In collaboration with Francesco Blasone and Enrico Pivato, we performed several simulations of the flow around a profile NACA 2410, exploring the effects that interpolation schemes and time integration algorithms have on the results. Indeed, by comparing different approaches, we've gained valuable insights into how these methods impact the accuracy and efficiency of simulations. In addition, we've thoroughly explored four RANS turbulence models: K-?, K-ω, K-ω SST and Spalart-Allmaras, each offering unique advantages depending on the specific flow scenario. Moreover, an introductory chapter has been entirely dedicated to the study of the grid independence coupled with some consideration over the mesh quality. To close the report also a brief analysis about the Strouhal number of the vortex shedding phenomenon obtained, as well as some comparison of the results with empirical one were added to validate further the methodology used and the outcomes of the simulations. We are proud of the progress we've made and the knowledge we've gained through this simulation study. Looking forward to applying these learnings to our future projects and continuing to push the boundaries of CFD research! #CFDSimulation #OpenFOAM #TurbulenceModels #NumericalMethods #EngineeringResearch #Aerodynamics

Determining the flow behaviour of tailings is no child's play. Here we see the modeling of tailings validated against a full scale plume. CFD simulation using FLOW-3D HYDRO's tailing's model makes it a simple affair to understand the phenomenon and can be used as an alternative to physical modeling to substantially reduce cost and time. #flow3d #cfd #flow3dhydro #tailings #waterandenvironmental #spillway #numericalsimulation
